1. INTRODUCTION
1.1 History
“Instituto
association
de
of
Telecomunicações”
four
institutions
(it)
is
a
private,
with
experience
not-for-profit
and
traditions
organisation,
in
research
an
and
development in the field of Telecommunications:
• “Instituto Superior Técnico” (IST);
• “Universidade de Aveiro” (UA);
• “Faculdade de Ciências e Tecnologia da Universidade de Coimbra” (FCTUC);
• "Portugal Telecom Inovação", (PTIn), ex. "Centro de Estudos de Telecomunicações"
(CET), the research unit of the incumbent telecommunications operator “Portugal
Telecom” (PT).
it is organised around three sites: one in Aveiro, in the University Campus, another in
Coimbra, in Pole II of the University of Coimbra and the third one in Lisbon, in Intituto
Superior Técnico. An external laboratory is functioning in Covilhã, in the University of
Beira Interior.
Setting up of it was the result of a 1.5 billion escudos (about 7.5 million Euros) grant
from Programme CIÊNCIA, through three contracts signed in 1991. This investme nt enabled new infrastructures to be built and research laboratories to be equipped at each
site.
Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994. Since
1995 it activities proceed regularly. Key developments in 2003 are sketched below leaving the details for the report of the scientific areas.
it statutes were first approved in 1992, modified in 1997 and modified again in 2003.
This report reflects the last version of the statutes.
1.2 Management
it is managed by a Board of Directors, elected by the General Assembly, and by site
management boards, which include the site members of the Board of Directors. Site
management boards enjoy ample freedom to deal with current affairs. The Board of
Directors meets at least once a month.

INSTITUTO
DE
TELECOMUNICAÇÕES
it scientific activities are overseen by the Scientific Board, which includes all it
researchers holding a Ph.D degree. The Scientific Board meets in Plenary or in
Committees, both permanent and temporary. There are two permanent committees:
Science and Technology Committee and Research Group Coordination Committee.
it Work Plan and the Annual Report are discussed with the Advisory Committee and
together with the Accounts (after legal certification) are subsequently submitted to the
General Assembly for approval.
The General Assembly met once informally and twice formally. Th informal meeting was
held at the Palace of S. Marcos, on February 14, to discuss and finalize the new it
Statutes. The first formal meeting took place on March 27, on the Meeting Room of the
Coimbra site, to discuss and vote (favourably) the new it Statutes, to aprove the Annual
Report and Accounts for 2002, and to elect the Board of Directors. The second formal
meeting was held on December, 19, on the meeting room of the Lisbon site, to discuss
and aprove the Work Plan and Budget for 2004, to aprove the opening of an it delegation
at the Escola Superior de Tecnologia e Gestão of the Instituto Politécnico de Leiria.
The plenary of the Scientific Committee met for the first time on May 23, in Hotel dos
Templários, Tomar, to discuss the Draft Proposal of the 2002 Annual Report, which
received a favourable opinion, to discuss its Rules of Procedure and to ratify the
Coordinators of the Scientific Areas. The Rules of Procedure were subsequently submitted
to electronic voting and approved unanimously.
On the same meeting the Scientific Board approved the list of senior it researchers.
The Science and Technology Committee met for the first time, on October 17, at Hotel
das Lezírias, Vila Franca de Xira, to discuss the new facilities to be implemented on the IT
web portal, to discuss the Draft Proposal of the Work Plan and Budget for 2003, which
received a favourable opinion, to discuss a proposal to open an it delegation at the
Escola Superior de Tecnologia e Gestão of the Instituto Politécnico de Leiria, which also
received a favourable opinion, to look into the request from Siemens SA to become an
associate of it. The committee also discussed at length the current finance situation and
looked for possible funding alternatives.
The Research Group Coordination Committee met for the first time, on December 12, at
Hotel das Lezírias, Vila Franca de Xira, to discuss the Work Plan and Budget for 2004,
which received a favourable opinion, and to discuss ways to improve it intersite and
intergroup cooperation.
The Board of Directors met once a month.
During 2003, due to funding situation, described in more detail below, there were no
meetings with the Advisory Committee.

1.3 Highlights of 2003
In the R&D scene 2003 may be shortly described as the “annus horribilis”. This
statement stems from the fact that the normal funding from the Fundação para a Ciência
e a Tecnologia (FCT) never came in. This includes both the basic funding and the
Programattic funding under the Associate Laboratory contract
As described in the 2002 Annual Report FCT was in arrears 560 k€ of which 211 k€
correspond to concluded PRAXIS projects, 140 k€ to the basic funding for the second
seme ster of 2002 and 209 k€ to the Associate Laboratory Programattic funding for the
second semester of 2002.
Following a series of meetings of the highest level which included one meeting with His
Excellency the President of the Republic, two meetings with the Minister for Science and
Technology and two meetings with both the President of FCT and the Manager of POSI
(Operational Program for the Information Society), where the funding situation was
thoroughly explained, during the second semester of 2003, and mostly during the last
quarter, FCT managed to pay its 2002 debts, By the year end FCT was in arrears 1.57
M€, of which 786 k€ correspond to basic funding,692 k€ to Programatic funding and 98
k€ to concluded or running projects.
Although FCT R&D funds have been hard to come by, the case of it is worse than most
other research units (which have already received all 2003 FCT funding, with possible
exception of projects) since its funds (together with another 2 Associate Laboratories and
15 research centers) are highly dependent on the POSI management. The behaviour of
the POSI management appears to be in sharp contrast with the continuous government
support of the information society.
As is to be expected such delays in payments, which have not been solved by the time
the report is being written (March 2004), had a devastating influence on it expectations
and plans for 2003. Using other funding sources it managed to keep the two tec hnicians
and two post-doctoral fellows admitted during 2002, but it would have been suicidal to
try to admit the personnel foreseen in the Associate Laboratory contract.
it searched extensively, and in a few cases sucessfully, for new source of funding, mainly
internationally. As a result there were 2 new projects plus a continuing project funded by
ESA and 4 new projects funded by the European Commission under the IST Programme
(of which 2 are been carried out under IST due to contractual uncertainities at the time
of signature). In addition a further 5 projects funded by the European Commission were
sucessfully negotiated and are due to start (or have already started) in 2004.

INSTITUTO
DE
TELECOMUNICAÇÕES
As stated in the 2002 Annual Report it submitted 10 proposals to a call issue closed on
the 27th of May 2002 of which 6 were sucessfull and started during the second semeter
of 2003.
There was no FCT Call for Proposals during 2003.
During 2003, 79 projects were active, 58 nationally funded and 21 internationally,
including:
•
30 projects funded by FCT (21 under the POSI program, 8 under the POCTI
program and 1 under the PNAT program);
•
6 projects funded by Agência de Inovação (AdI);
•
6 projects funded by it itself
•
6 projects funded by Portugal Telecom Inovação;
•
4 projects funded by Conselho de Reitores das Universidades Portuguesas
(CRUP);
•
2 projects funded by FEDER-PRAI-Centro
•
2 projects funded by the Portuguese Navy;
•
2 projects funded by ICP/ANACOM;
•

Table 1– Backtrack of number of active projects in it, according to type of funding.
The simple listing of active projects is somewhat misleading since it does not reveal the
fact that, due to delays in payments, a significant number of projects (funded by FCT
under the POSI program) are only nominally active, waiting for last payments.
During 2003 it hosted the following international conferences and seminars, which
altogether attracted more than 900 participants:
• I Symposium on Enabling Optical Networks, held at the Aveiro site, on June 16th, with
about 60 participants;
• IST Mobile & Wireless Communication Summit, held at the Congress Centre in Aveiro,
in June 15 to 18, with about 400 participants. The fact that organization of the 12th
venue of this prestigious conference was awarded to it demonstrates its recognition in
the field of mobile communications;
• Conftele’2003, held at the Congress Center in Aveiro, in June 18th to 20th, with 160
participants, which presented and discussed 133 papers. The conference programme
included 3 keynote addresses by leading international experts in the field and a short
course (on the afternoon of the first day) on Digital and Interactive Television;
• EMMCVPR’2003
Energy
Minimization
Methods
in
Computer
Vision
and
Pattern
Recognition, an international workshop, held in Lisbon on July 9th, with 70 participants;
• Wireless Internet: Network Architectures, Quality of Service, Services and Applications,
a Summer School held at IST (Lisbon) on July, 21s t to 25th, with 40 participants;
• HSNMC’03 – 6th IEEE International Conference on High Speed Networks and Multimedia
Communications, held at Hotel Atlântico, Estoril, on July 23rd to 25th, with over 100
participants;

INSTITUTO
DE
TELECOMUNICAÇÕES
• MTPT – Advanced School and Workshop on Mathematical Techniques and Problems in
Telecommunications, held in Instituto Politécnico de Tomar, on September 8th to 12th,
with about 70 participants.
To reflect it 2003 activity some tangible objectives were defined in the Work Programme
and Budget for 2003.

Table 2- Foreseen and achieved scientific output in 2002.
The increase in the number of Final Year Project Reports is mainly due to the fact that, in
contrast with 2002 that was used for the prediction, almost all reports are now accounted
for. The large number of MSc thesis partly compensates the low number of PhD thesis.
Anyway the number of PhD thesis is roughly double the number of PhD thesis concluded
in the past 8 years. Although the number of concluded theses is below the expected
value, we note that at the time of writing, a significant number of theses has already
been concluded or submitted.
The number of papers published in conferences proceedings increased due, partly, to
Conftele 2003.

4.1.3 Summary of Research Achievements
Research work in the Wireless Communications Scientific Area of it covers the main
aspects
related
to
the
air
interface
in
wireless
communications
and
supporting
hardware/software. Activities fall within the following five general topics:
-
Antenna Analysis and Design;
-
Physical Modelling and Wave Propagation Characterisation;
-
Wireless Circuits and Devices;
-
Transmission and Reception Systems;
-
System Planning and Resource Management.
4.1.3.1 ANTENNA ANALYSIS AND DESIGN
Work on antennas may be grouped under two main topics: personal small-terminal
antennas for frequencies below 6 GHz, and millimetre wave antennas for 4th generation
mobile communications and for space applications. The first topic falls within the
European funded FLOWS project, and the second topic falls within the FCT/POSI funded
ILENA project, and the ESA funded ILASH project.
Work has continued on new antenna proposals for integration into future personal multimode multi-antenna communications terminals that explore MIMO techniques. Two
approaches were used for these antennas: the multi-band antenna approach, and the
ultra-wideband antenna approach. Printed antenna technology was used for both types of
antenna. Koch pre-fractal based antennas were designed fabricated and measured,
covering the GSM1800, UMTS and HiperLAN2 bands. A remarkable miniaturization has
been achieved. Also single patch single feed elements with slots, and integrated three
patches with three feeds have been successfully considered for the triple-band design. On
the ultra-wideband approach, work continued on single-arm spiral antennas with reduced
ground plane, now to study experimentally the effects of proximity to mutually
neighbouring spirals in MIMO configuration, and the influence of the terminal itself.
Activity on millimetre wave dielectric antennas was focused on double material lenses
either with on-axis feeds, or with off-axis feeds for space applications. A comprehensive
literature survey was carried out to identify new approaches for the efficient analysis of
this type of lenses, with a view to the development of a fully featured lens design
software tool. Work started on a spectral domain method to evaluate its appropriateness
for complex lens antenna analysis and its comparison with classical methods based on
Geometrical Optics and Physical Optics. Work also continued on the evaluation of lens
moulding fabrication technique.

TELECOMUNICAÇÕES
In parallel with these activities, the millimetre wave anechoic chamber is being up-graded
in the framework of the FCT/POCTI funded Project COMPACT to integrate new hardware.
A first version of the new antenna measurement control software was completed and
successfully tested.
4.1.3.2 PHYSICAL MODELLING AND WAVE PROPAGATION CHARACTERIZATION
Work in this sub-area addresses both guided-wave and non-guided wave phenomena
characterization which includes radiowave propagation modeling.
Electromagnetics of Complex Media
One very strong work topic is related to electromagnetics of complex media: artificial
materials obtained by random or periodic inclusion of metallic or dielectric particles into a
host dielectric media to obtain unconventional electromagnetic properties not commonly
found in natural materials. Performed work includes both characterization of the media
itself (including the relation between inclusion shape and periodicity, with material
macroscopic electromagnetic behavior), and wave propagation in guided wave structures
using these type of materials.
Artificial dielectrics with periodic lattice were characterized both in the low frequency limit
and for arbitrary frequency to characterize its band-gap filtering characteristics. New
techniques were developed in both cases for very efficient computation of these materials
characteristics. Attention was dedicated to the characterization of frequency selective
surfaces (FSS), to unbounded full 3D wire media with connected as well as non-connected
wires, and to the characterization of resonant ring inserts positioned inside cut-off
waveguides exhibiting negative permeability properties.
Complex media is also of interest in the design of new waveguide components for
microwave and millimeter-wave devices. Work pursued on characterisation of dispersion,
guidance and leakage properties in open 3-dimensional planar chiral and pseudochiral
(omega) waveguides, and in chiral optical fibres..
Propagation in Optical Fibers
Work was done on soliton dynamics in dispersion-varying compensating fibers. The
objective was the analysis of new transmission schemes where the normal dispersion
compensating fiber (DCF) is replaced by dispersion-varying compensating fibre (DVCF)
with
decreasing
or
increasing
dispersion
profiles.
In
the
framework
of
project
TRANSPARENT, it was shown that the dynamic behavior of soliton pulses in such systems
16
may produce a performance improvement for specific profiles. Analytical and simulation
studies will follow, in order to identify the best dispersion profiles for DVCFs and a
generalization of the procedure to be applied in different dispersion maps.
Radiowave Propagation Modelling
Activities span over two main sub-topics:
-
Propagation in complex environments (propagation through walls, microwave and
millimetre
wave
propagation
in
indoor
and
urban
mobile
communications
scenarios, and propagation through vegetation);
-
Microwave radio links (land and satellite).
Work continued on quantification models for building wall penetration loss when window
apertures are present in land mobile communication scenarios (GSM and UMTS). This
work was awarded the Luis Vidigal Prize from the Department of Electrical and Computer
Eng from IST.
In the framework of mobile directional channel characterization a few field measurements
were made using a channel sounder. The measured data was explored by the SAGE
algorithm to retrieve ray parameters. Some studies were developed to gain a better
understanding of the method limitations and to get best results for ray parameters
retrieval in real scenarios.
Relationships were established between adaptive antennas beamformimg and wideband
directional channel models for several scenarios in micro- and macro-cells;
With
respect
to
millimetre
wave
mobile
communications,
work
was
focused
on
experimental Channel Impulse Response (CIR) characterisation of indoor scenarios at 40
GHz. Measurements were carried out in a wide indoor sports pavilion, and in a office
meeting room. CIR was calculated from spectral analysis of measured frequency domain
results obtained with the millimetre-wave front-end and other equipment developed for
the ACTS-SAMBA project Trial Platform. These CIRs and power delay profiles were
compared against those obtained from a ray tracing-based prediction tool.
Models were developed for fading characterization in broadband systems, enabling an
accurate estimation of fading margins for several environments;
Propagation through vegetation was also a strong area of research. Work continued on
the characterisation of absorption, scatter and depolarisation of the incident microwave
17

DE
TELECOMUNICAÇÕES
and millimetre wave signals by vegetation media. Members of it participated in a UK
Consortium, together with Rutherford Appleton Laboratories (RAL), Universities of
Glamorgan and Portsmouth, and QinetiQ, to perform an extensive programme of
measurements aimed at the establishment of a narrow band prediction model for
propagation through vegetation. Work also pursued on the development of a wideband
(1-60 GHz) propagation model more suited for the characterization of high data rate
wireless services influenced by vegetation as in sub-urban or rural areas. Research is
continuing also on the development of a Discrete Radiative Energy Transfer generic model
for non-homogeneous random vegetation media, drawing on the relations between its
parameters and vegetation species.
On Earth-Satellite propagation studies, an analogue beacon receiver was changed to
receive a Hot-Bird6 Ku band. A versatile software using FFT based techniques to estimate
co-polar and weaker cross-polar channels was developed. The study of an alternative
equipment based on digital IF sampling and DSP techniques was initiated and is under
development. Software for the analysis of beacon propagation data on the framework of
the pre-processing stage was developed.
Work continued on the ITEM project sponsored by Vodafone, aiming at contributing for
public awareness of basic concepts related to electromagnetic radiation and population
exposure in mobile communications. The public website has been continuously updated
with on-line
measurements from autonomous remote sensors, and portable unit
measurements by the project team. Individual results are provided for more than 140
sites in Portugal, along with global cumulative results.
4.1.3.3 Wireless Circuits and Devices
Research work performed in this sub-area can be grouped under two general topics, one
related to microwave circuit design, and the other to computer aided design of
microwave/RF circuits and systems including simulation techniques and system/device
modelling. In both cases, the underlying applications fall within the wireless area.
RF and Microwave Circuit Design
One main topic of research is related to active and passive filters, using different
technologies. Active and passive bandpass filters were designed for 30GHz (Galactic
project) with PM-HEMT 0.25um GaAs technology for comparison with coupled lines filters
that were designed for the low cost LTCC (low temperature cofired ceramics). The LTCC
coupled lines filters were fabricated and tested (Galactic project). To reduce the filter size,
LTCC filters with defected ground structures were also designed and their performances
18
compared with the coupled lines filters. The design includes analysis and optimization of
the yield for fabrication, in order to prove the possibility of using such substrates in
30GHz for high volume and low cost production.
Other important research area is related to BiCMOS and CMOS RF circuits. Monolithic
integrated LC voltage controlled oscillators (VCO) were fabricated on BiCMOS 0.8um
technology for 2.4GHz and uses monolithic spiral inductors. Also single ended and
differential low noise amplifiers (LNA) were fabricated on CMOS. These LNAs were
integrated on 0.35um CMOS technology and were designed for the 2GHz band.
Beyond that, the front-end of an S-band wireless transceiver was designed and
implemented in a 0.35um CMOS chip. That included a common-source LNA, two CMOS
quadrature mixers, one CMOS RC VCO with quadrature differential outputs, polyphase
filter, and an output driver amplifier. Studies concerning the possibility of using SiGe
monolithic technology for active filters applications were performed. First designs of LNA
amplifiers to be used on those active filters were obtained. A grounded and a floating
active inductor for 2GHz was also fabricated with CMOS 0.35 um process (ACTFIL
project). Based on the obtained results, new active inductors were designed, fabricated
and measured (AME project).
Aspects concerning high frequency on-wafer measurements up to 6GHz with silicon
substrates were also addressed. The measurements included S-parameters, noise figure,
output power, distortion and phase noise.
Computer Aided Design Tools for RF/Microwave Circuits and Systems
Electric models were obtained up to 6GHz for spiral inductors, poly capacitors and
resistors on BiCMOS and CMOS technology.
Due to the inefficient models supplied by the CMOS MMIC foundries, semiconductor and
passive devices models for CAD programs were developed in it. Due to the low resistivity
of Si substrates, techniques for experimental characterization of MMIC components and
sub-circuits were studied to support these modelling activities.
Nonlinear distortion and efficiency modelling of power amplifiers based on GaN HEMT
microwave devices had also increased. Its main objectives were the equivalent circuit
nonlinear model formulation and extraction of a power GaN HEMT device.
In what behavioural modelling activities at the system level are concerned, our efforts
have been devoted to formulate a general nonlinear dynamic model whose extraction is
19
INSTITUTO
DE
TELECOMUNICAÇÕES
feasible with the present RF laboratory instruments or circuit simulation tools. For achieve
that goal, a general non-recursive polynomial filter with enforced orthogonality for a
certain class of multisine signals was studied.
With respect to computer aided design tools of RF/microwave circuits, main research
efforts have been directed to the co-simulation of wireless systems subject to multicarrier
modulated signals. This consists in a very promising complex envelope driven simulation
method, in which both generic behavioural and detailed equivalent circuit level models are
supported.
4.1.3.4 Transmission and Reception Systems
Research work performed within this sub-area includes the following topics: UMTS
capacity enhancement techniques, channel estimation techniques in satellite and land
mobile communications, video bit stream video protection in wireless transmission, and
signal processing in synthetic aperture radar.
Wireless techniques such as space-time coding, beamforming (adaptive antennas) and
minimization of multiple-access interference for the downlink of WCDMA were explored at
it in the framework of IST-SEACORN project for enhancing the capacity of the UMTS
system. The WCDMA UMTS system was studied at the Link Layer level to extend its
capabilities, and the work included the development of a complete system simulator.
Spectrally efficient modulation techniques like continuous phase modulation or QAM
modulations were also studied to pursue performance enhancement in the future UMTS
system.
Another topic of research was related to channel estimation techniques in satellite mobile
communications. Solutions were proposed within the stochastic nonlinear filtering
framework to address the problem of detection of multi-level signalling schemes, namely
the 16-DAPSK modulation, in the following environments: channels affected by Doppler
effect, and channels disturbed by fading. An algorithm for Doppler frequency and
Frequency-rate was proposed for non-geostationary satellite communications. Some work
was dedicated to the problem of channel estimation in multi-carrier systems. Attention
was also devoted to the application of nonlinear filtering techniques in CDMA systems. In
particular, the problem of fast acquisition of code and frequency in GPS receivers was
considered.
The performance of TCH codes was evaluated using efficient simulation techniques
considering both simple and mixed channels using Markov models. The taxonomy of those
channels was performed and new upper bounds were analytically obtained for this class of
TCH codes that agree with previous simulation results.
20
New convolutional codes and new turbo codes were developed based on TCH codes, and
they were evaluated in terms of their performance and upper-bounds. The codes were
applied in a CS-CDMA system in which the functions of spreading and coding were
realized simultaneously by the same code. Multi User Detectors (MUD) were implemented
for the UMTS system and also for the CS-CDMA systems using turbo-TCHs and turbo
super-orthogonal codes.
Implementation of Power Control schemes in a previously developed simulator for the
UMTS system showed that the performance of this mode of operation strongly depends on
multi-path interference. Different diversity schemes using several transmission antennas
were studied: STD (selective transmit diversity using 2 antennas) , STTD (space time
transmit diversity using 2 antennas), STBC (space time block coding using 4 or 8
antennas) and hybrid schemes with any combination of STD with STTD or STBC.
Implementation of multidimensional rotation of symbols or CRM (Complex Rotation
Matrix) schemes were also studied as a form to combat fading channels.
In respect to video bit stream protection in wireless transmission, the research work
spanned through the following topics: joint source-channel coding and modulation;
network adaptation of video streams; statistical multiplexing of TV and data signals;
MPEG-4/AVC video transportation over TV packet based transmission.
In Synthetic Aperture Radar, the activity continued on the characterization of the ''blind
angle ambiguity problem'', on the absolute phase estimation in interferometric SAR
images, and on speckle noise filtering. Besides these research topics, the problem of
linear unmixing in hyperspectral data was also addressed.
4.1.3.5 System Planning and Radio Resource Management
Research work in this sub-area covered traffic-based UMTS system capacity studies, and
services and applications characterization.
Different types of circuit switched traffic and possible future scenarios of multi-service
traffic were used for evaluation of UMTS FDD system capacity. A software tool was
developed with this objective. In the absence of UMTS traffic data, GSM/GPRS data was
used instead to analyze combined data and voice traffic, as well as to analyze the effect
of the double layer structure of 900/1800 MHz GSM on network management. With the
same objective, the problem of dynamic channel allocation was also addressed, based on
measurements performed on a real GSM network.
Another software tool was developed to simulate the air interface of UMTS-FDD, enabling
the analysis of traffic aspects as well as load and handover ones. Models were established
21
INSTITUTO
DE
TELECOMUNICAÇÕES
for traffic generation for UMTS, including a large variety of services and applications,
enabling a better estimation of traffic, as well as an improved evaluation of load;
Research on Enhanced UMTS services and applications characterisation, classification, and
deployment scenarios has been performed within the IST-SEACORN project. Contributions
have been given on multi-service traffic engineering in Enhanced UMTS. New approaches
were proposed, based on practical results obtained for GPRS and UMTS. These aspects
are being incorporated into the IST-SEACORN system level simulator, and new results are
being produced.
Work on Cost/revenue performance of Mobile Broadband Systems (MBSs) was concluded
and published.

incoming signal to baseband (direct conversion) where its quadrature
components are sampled. In this type of receivers carrier
synchnronization is replaced by channel estimation, which consists of
the following tasks: (i) estimation of the phase drift due to Doppler
effect and/or frequency poor alignment between oscillators; (ii)
estimation of the channel time-varying gain provoked by fading and/or
shadowing. The problem of channel estimation presents new challenges
with the emergence of mobile personal communications based on, for
example, non-geostationary satellites, which are affected by significant
Doppler frequency shifts. In these cases, the channel is strongly nonstationary (even with very short time intervals), leading to the need to
update phase and gain estimates within the symbol interval. Channel
estimation in mobile digital communications is a relevant research
subject not only from the applications point of view but also by its
theoretical and conceptual aspects. This project proposes to resume
previous work in this area by focusing namely on the following aspects:
a) synthesis of new algorithms for the simultaneous joint channel and
clock estimation, and symbol detection based on stochastic nonlinear
filtering; b) development of new open-loop frequency and frequencyrate estimators; c) application of the above-mentioned algorithms in
scenarios of practical interest, such as the mobile digital
communications with non-geostationary satellites; d) application to
spread spectrum and
multicarrier systems where significant
improvements are foreseen.

Multi-service cellular planning for mobile communication
The project focus is cellular planning for multi-service mobile
communications systems (3G, 3.5G and 4G) in the aspects of
characterisation and classification of services and applications, resource
re-use, teletraffic, cost/revenues and signal processing. Research is
focused on i) Classification of new mobile and wireless services and
applications, ii) Characterisation of applications through the
identification of relevant parameters and the evaluation of their range of
variation, iii) Identification of deployment scenarios, and realisation of
forecasting studies for Internet and Multimedia traffic, iv) developing
models for the impact of mobility in multi-service time -based and nontime based (real and non real-time) traffic, in the aspects of blocking
and delay and v) cost/revenue optimisation. Original contributions will
be pursued on developing and characterising these new applications and
on the tele-traffic performance of advanced wireless and mobile
networks (e.g., using models as the Markov- modulated Poisson
Process/Bernoulli-Poisson-Pascal one or the ones for self-similar traffic).
Cellular planning optimisation will be addressed through the inclusion of
traffic aspects in a cost/revenue model and also into a cellular Mobile
Broadband System planning tool develloped within our group.

The main objective of this project consists of studying and developing
error resilient video coding algorithms and transmission techniques
appropriate for high frequency (HF) carriers allowing attaining high
quality videoconference services in long distance communications. The
short wave channel imposes several hostile propagation conditions that
will affect video signal communications. Furthermore, the very low
throughput bit rate (12800bps) provides a strong limitation on video
communications. This project will attempt to overcome those appointed
drawbacks.

Optimização de Amplificadores Linearizados em Presença de Sinais
Reais Multi-Tom
Os sistemas actuais de comunicações via rádio estão limitados em
grande parte pela distorção não linear que os componentes que o
constituem geram. Apesar dos esforços recentes no estudo da distorção
não linear em amplificadores, misturadores etc, sujeito a sinais reais de
telecomunicações, esses são normalmente virados para testes ideias de
laboratório, como sejam os testes a um tom e dois tons sinusoidais.
Como se pretende que os sistema de rádio emitam informação real e
não ideal, o estudo destes sistemas quando em presença de um sinal
real é fundamental para o correcto projecto dos mesmos. Devido à não
existência de sobreposição e proporcionalidade nestes sistemas não
lineares, a extensão dos testes ideais para as situações reais não é
imediata, pelo que o estudo do comportamento dos sistemas não
lineares em presença deste sinais é o principal objectivo deste projecto.
Pretende-se com este trabalho determinar qual a relação entre a
distorção medida num sistema não-linear geral (cuja concretização de
maior interesse é o amplificador isolado ou com linearização externa)
sujeito a dois tons e a realmente observada no mesmo sistema sujeito a
uma excitação real, i.e., a um sinal de informação constituído por uma
portadora de RF modulada por um sinal de banda-base aleatório. Sendo
já conhecida solução para o problema mais simples do regime de sinal
fraco e sem memória, pretende-se estender estes resultados ao caso
dois amplificadores de potência (portanto em regime de sinal forte) e
com memória.
OPAMS/POCTI/ESE/37531/2001
Optimum Power Amplifiers for Modulated Signals
Recent wireless communication systems demand very high signal to
noise ratios (SNR). However, the continuous improvement of power
amplifier (PA) efficiencies has led to an increased nonlinearity behavior,
severely degrading system's fidelity. One former way to minimize this
effect consisted on using constant envelope modulation systems,
31
INSTITUTO
DE
TELECOMUNICAÇÕES
trading higher spectrum bandwidths for lower distortion. Unfortunately,
spectrum bandwidth became a scarce precious good imposing nonconstant envelope modulation schemes. Therefore, the PA nonlinearity
is nowadays of primordial importance to the maximization of the SNR in
this type of telecommunication systems. The main objective of this
project is to propose new design PA procedures intended to improve
linearity in presence of complex communication signals of non-constant
envelope. To fulfill this goal, the time and frequency domain properties
of the complex modulation techniques will first be studied. Special
attention will be given to the peak to average ratio of the excitation's
time description, and to its complex spectral representation, mainly to
the correlation between its different spectral lines. The information
gathered with this analysis, associated to the previous background of
the authors, will inspire improvements to the existing nonlinear RF
circuits' simulation tools, or even to the proposal of novel nonlinear
analysis methods, specially tailored for the type of modulated signals
under study. With the aid of the proposed simulation techniques, and
the knowledge of the driving signal statistics, the nonlinear behavior of
PA will be studied when in the presence of complex communication
signals. The correct understanding of this behavior will end up in the
suggestion of a new procedure for the design PAs optimized for
linearity. Finally, a PA prototype specially designed for handling multitone complex modulated signals will be implemented and tested. That
will serve as the practical validation of the proposed theoretical analysis
methods and circuit design tools.

Signal and Image Processing in Synthetic Aperture Radar
This project addresses the following research topics topics in synthetic
aperture radar (SAR): (1) Moving target detection and estimation; (2)
Interferometry; (3) Image restoration. (1) Moving target detection,
estimation, and imaging is important for wide area surveillance systems
with limited revisit times. (2) The problem of interferometry is
essentially the estimation of absolute phase from a pair (or more) SA
images. Topographic maps are then obtained with basis on the
estimated absolute phase images. (3) The pixel amplitude of SA images
are, under mild conditions, a sample of a Rayleigh random variable.
Therefore, the image amplitudes corresponding to an homogeneous
region exhibit random fluctuations, termed ''speckled noise''. The
following goals have been pursued, concerning each of the three
referred topics: (1) Developing solutions to the so-called ''blind angle
ambiguity'' problem. It means that using just an antenna it is
impossible to infer the direction of the velocity vector. One way to
remove the blind angle ambiguity is to make simultaneous bistatic SA
measurements with two different antennas. Aiming at the resolution of
the blind angle ambiguity problem with only one antenna, it is proposed
the exploitation of recent results, derived by the proponents, on the
relations between the received signal and the moving target velocity.
(2) Developing Bayesian approaches to the absolute phase estimation in
the presence of discontinuities. The inclusion of discontinuities is
relevant to obtain meaningful estimates. On the other hand, most
methods proposed in the open literature do not take discontinuities into
account. (3) Developing Bayesian approaches to the amplitude
restoration that, as in item (2), take the amplitude discontinuity into
account.

Simulation of Enhanced UMTS Access and Core Networks
SEACORN provides a fundamental contribution to the evaluation and
development of Enhanced UMTS networks. It covers several aspects
starting from the definition and characterisation of services and user
profiles, including the modelling of the user's behaviour with respect to
mobility and multimedia activity, and finally considering the
optimisation of the networks from both points of views: the operator's
and manufacturer's view of limiting the infrastructure and maintenance
costs and the user's view of being provided with high quality services

mobile communications area. That is, besides giving inputs to the
development of 4th generation systems, it is also expected that it will
contribute to the deployment of systems that are very close to
completion of their standardisation phase, like UMTS and HIPERLAN 2.

Table 19 – Non-permanent Collaborators working in the Optical Communications Area
In the following, the achievements in the OCarea are grouped, under three sub-areas:
-
Optical Components and Subsystems
-
Optical Communication Systems
-
Optical Networking.
4.2.3.1 Optical Components and Subsystems
The work carried out in this sub-area concentrated on the modelling, performance
evaluation, optimisation and implementation of key components and subsystems for alloptical Networks.
In a subject with impact in many sub-areas of optical communications, the activities
concentrated in the study, implementation and test of fibre Bragg gratings (FBG) for
WDM and CWDM system. A specific activity on this subject, consisted on the study of
dynamically adjustable chromatic dispersion compensators, based on chirped FBGs. It is
known that environmental variations, such as changes in temperature can cause
variations in the system overall dispersion. To overcome this problem, tuneable
dispersion compensators are needed especially for high-speed systems. The adjustable
chromatic dispersion compensators are achieved by adjusting the chirp of the FBG with
an externally applied perturbation like temperature (gradient) or strain perturbation.
In the area of arrayed waveguide gratings (AWG), characterisation of different
techniques for implementation of these devices with flat frequency response was
performed and the impact of fabrication errors on AWG frequency response was
analysed.
During the year of 2003 we have started work on specially doped fibres for amplifiers
applications. The preliminary tests focus on the mechanical properties of the fibres doped
61
INSTITUTO
DE
TELECOMUNICAÇÕES
with Erbium and Thulium for the L and S bands, respectively. Future tests will concern
the reshaping of the fibre spectral properties.
Work has also been done on the expansion of the amplification band into the L band. One
L band EDFA, with very high gain and flatness in saturated regime, has been developed
and characterized.
Directly modulated lasers for metropolitan area networks utilizing negative dispersion
fibers were optimized and general features of optimal lasers for dispersion supported
transmission systems were assessed.
Analysis have been performed on modified distributed feedback (DFB) laser structures,
namely
multiple-phase
shifted
(MPS),
distributed
coupling
coefficient
(DCC)
and
amplitude modulated grating DFB lasers. In the latter a slow variation, linear or not, of
the grating amplitude was considered. The impact of structural parameters on laser
performance, either in threshold and above-threshold conditions, was carried on using
matricial techniques (Transfer Matrix Method). Special attention was given to the
possibility of achieving the single-longitudinal mode (SLM) operation in the abovethreshold regime.
During the year 2003 the analysis and simulation of PIN and APD devices continued. The
simulation tools previously developed have been updated in order to take into account
some specific situations. One such case is the study of the frequency response of
separate absorption multiplication avalanche photodiodes when the light is incident from
either side of the device. The effect of the wavelength of the light on the device's
bandwidth was also investigated.
Great efforts have been directed towards the development of subsystems for achieving
transparency in all-optical networks in the areas of OADM, wavelength converters and
fibre Bragg gratings. A new technique, based on broadband orthogonal pumps together
with semiconductor optical amplifiers and dispersion shifted fibres, was developed to
improve the range of wavelength converters, based on the four wave mixing process.
In the subsystems area, various optical add/drop multiplexers (OADM) structures based
on AWG were analysed and their performance optimised, when operating in WDM optical
networks. Validation of the probability density function of the output current of optically
pre-amplified receivers with arbitrary optical filtering and transparent optical networks
was also achieved through Monte Carlo simulation.
4.2.3.2 Optical Communication Systems
In the field of optical communication systems, analytical and simulation work was carried
out to characterize analytically the self-phase modulation (SPM) impact on cross-phase
modulation (XPM) -induced degradation in dispersion compensated WDM systems and to
62
assess the influence of dispersion slope compensation on the XPM-induced degradation in
dispersion compensated WDM systems.
Advanced modulation formats, namely phase shaped binary transmission, enhanced
phase shaped binary transmission, alternate mark inversion RZ, and duobinary carrier
suppressed RZ with strong optical filtering were investigated for use in dense WDM
(DWDM) systems with optical dispersion compensation. A generalized reduced model for
performance assessment of optical line coding formats in dispersion managed systems
was also developed. This model describes the performance limitations imposed by group
velocity dispersion and self-phase modulation in these systems. A novel, simple and
generalized expression for the performance assessment of optically amplified receivers
valid for arbitrary coding formats was proposed.
Research has been pursued on the topic of soliton dynamics in dispersion-varying
compensating fibres (DVCF). The objective of this work is to analyze new transmission
schemes, where the normal dispersion compensating fibre (DCF) is replaced by a DVCF,
hoping to identify an optimal dispersion profile. A possible analytical approach to the
solution of this problem was presented and discussed in the workshop on Mathematical
Techniques and Problems in Telecommunications, at Tomar.
Communication systems using optical single side band transmission technique (OSSB)
were investigated. This transmission technique has advantages for upgrading the
capacity of the existing fibre networks. Novel Microwave Monolithic Integrated Circuits
(MMICs) were studied and implemented to generate OSSB signals. Work in this sub-area
included also the optimization and implementation of electrical equalizers to compensate
the fibre dispersion in 10 and 40 Gbit/s OCsystems.
Orthogonal modulation techniques are being developed for high bit rate optical routing
proposes. This combined modulation formats have been proposed recently to optically
labeling of high-speed IP packets through DWDM networks. In this technique, the packet
reading and routing are carried out directly in the optical domain. The use of optical label
swapping allows the set up of optical paths along which the payload data is routed
transparently, avoiding the electronic payload processing. In the studied orthogonal
modulation technique, while the label is modulated in FSK (frequency shift key) format,
the IP payload is modulated in ASK (amplitude shift keying).
Free space optical transmission has been simulated. We have implemented a numerical
model to simulate the propagation of a laser beam through the atmosphere. The
introduction of this model in a photonic simulator allowed us to estimate the performance
of free space OCdata links. This model allows the study of correlations between BER and
atmospheric
variable,

rain or fog. All these variables are responsible for the degradation of the link quality due
to absorption, scattering, scintillation and beam wander.
4.2.3.3 Optical Networking
In the field of performance monitoring, techniques were developed for modelling the
asynchronous performance monitoring method. This technique has great practical
potential since it can be used in transparent optical performance monitoring, without the
need of opto-electronic conversion.
Investigation of the physical level limitations of transparent optical networks (TON) was
performed. In this field, a Gaussian approach for the performance assessment of optical
multiplexer / demultiplexer concatenation in those networks and a method to obtain the
TON’s Q-factor, which takes into account the effects of inter-symbol interference,
accumulated noise and crosstalk, were developed. Performance of TONs based on optical
add-drop multiplexers using AWGs, in presence of fabrication errors, was also analysed.
The OCDMA technique can provide simple network management and multiple access in
optical networks. Theoretical studies were carried out in order to implement a
demonstrator for high data rates and moderate distances. Also, some of the all-optical
routing techniques were observed and a new technique based on OCDMA headers was
proposed. Other techniques of orthogonal modulation formats were studied for use in
routing nodes.
In the field of radio over fibre, optimized wavelength interleaving techniques were
demonstrated and its benefits studied.
Research was also carried out on nonlinear effects in IP-over-WDM Networks. The
objective of this work was to develop a methodology for evaluation of the influence of
fibre nonlinear effects on the performance of IP-over-WDM networks, through the
estimation of the packet error probability caused by nonlinear effects as a function of IP
traffic characteristics and network critical parameters. A numerical method has been
identified, and this is now being tested with typical parameters for core and metro
networks, taking also into consideration different switching types.

and analyse optical intensity modulated signals with a 10 Gbit/s bitrate.
Both functions will be integrated in a late prototype, where the
developed functionalities will be demonstrated. The developed
functionalities are in agreement with the needs of the future photonic
networks, where the processing and analysis of the signals will be
realized completely in the optical domain.

Chromatic dispersion in nondispersion-shifted fibers, limits significantly
the transmission distance in optical systems operating at data rates in
the range of 10Gbit/s, or higher, per wavelength division multiplexing
(WDM) channel. This limitation is due to intersymbol interference (ISI),
which leads to degradation on system performance. Given the large
quantity
of
nondispersion-shifted
fibre
currently
installed
in
telecommunications network, overcoming this limitation has become a
very important scientific and commercial goal. One of the most
promising techniques to overcome the dispersion limit is the
transmission of optical single sideband (OSSB) signals. This project will
develop OSSB transmission and receiver systems capable to upgrade
the capacity of the installed fibre with transmission rates exciding the
10 Gbit/s.

WDM soliton communication systems; (ii) amplification of solitonlike
pulses in erbium- doped fiber amplifiers; (iii) soliton switching in
nonlinear fiber couplers; (iv) chiral solitons, i.e., solitons in chiral optical
fibers.
DOPTNET/POSI/CPS/42073/2001
Highly Dispersive Pulses in Dense WDM Optical Network
Project is aimed to answering some practical questions concerning very
high capacity optical networks, namely what is the maximum capacitylength product attainable in a connection, what are the requirements for
the switching/cross-connecting nodes and the degradations effects
induced by the optical wavelength converters presence.

Wavelength Division Multiplexing and OCDMA for broadcast and Select
Networks
This project aims to demonstrate a network based on Optical Code
Division Multiple Access (OCDMA) where the multiple access to the
media is free and based on an Broadcast/Select (B/S) Architecture. This
type of transmission methodology is not new, however, the approach
that is aimed within this project tries to innovate either in the network
architecture or in the code utilization and limitations. With the proposed
architecture, we will try to achieve further distances by concentrating
the spectrally sliced spectrum in a controlled block and using more pure
spectral sources, lasers with narrow spectral linewidth. Only one of
these nodes will be present in the network, simplifying controlling
processes, increasing network stability and decreasing nodes cost. In
the user node, will try to have as much simplic ity as it is possible, by
having the simple and cheaper, and totally optical in order to reduce the
complexity of the optics and electronics. By mixing the concepts of
Wavelength Division Multiplexing (WDM) and OCDMA, we aim an
optimized code that will result in an optimum number of users per band
and the band optimum parameters, always having in mind the
optimization of the network cost and complexity (number of lasers and
complexity of the coder/decoder parts). Besides the already presented
objectives, we will try to develop an totally optical router for this type of
networks that will migrate codes in between bands and codes available
in the network or neighboring networks. Also, based on the main
components limitations will try to suggest the best utilization and
limitations of this type of network when compared to other equivalent
configurations. In summary, this project will try to improve the concept
aiming to achieve a more efficient and less expensive approximation,
making this type of network more appealing for practical and wide
implementation. Doing this we will also achieve better domain in the
design and implementation of fiber bragg gratings in order to have the
best results for this type of application.

The work in the area of Networks and Multimedia is organized in several topics:
Architectures and protocols;
-
Traffic engineering;
-
Network operations, Management, and planning;
-
Impact of Telecommunications in Society;
-
Processing, analysis and coding of audio and visual information;
-
Pattern recognition and automatic learning;
-
Speech analysis and recognition.
In the following, we briefly summarize the main achievements in each of these topics.
4.3.3.1 Architectures and Protocols
Routing protocols - Research focused on the convergence properties of path- and
distance-vector
protocols
in
a
broad
range
of
operational
environments,
from
performance-oriented intra-domain routing to policy-oriented inter-domain routing in the
Internet. A non-classic algebraic theory of network routing was developed which unifies
these seemingly unrelated routing paradigms and establishes fundamental results. The
theory views routing with path- and distance-vector protocols as a generalization of
shortest-path routing. Instances of the theory have provided guidelines for the complex
problem of inter-domain policy-oriented routing with the Border Gateway Protocol.
IPv4-IPv6 transition scenarios - The evolution of IP networks from IPv4 to IPv6 protocol
is being addressed by investigating architectures and protocols that can provide existing
and new services in an integrated way and that can work over the most promising
evolution scenarios where both protocols must exist. Particular attention is being devoted
to the combination of DNS, multicast and mobility over both a single autonomous system
and multiple autonomous systems. A set of solutions to provide mobile IP over IPv4-IPv6
transition scenarios was already investigated and this work is being subject of
publication.

INSTITUTO
DE
TELECOMUNICAÇÕES
Heterogeneous networking issues - The work performed was centered on heterogeneous
networking issues, mainly on QoS aspects, and the integration of QoS with service
concepts. A trial site and a QoS Broker were developed. On-going activities are: overall
architecture of heterogeneous networks, including broadcast technologies; QoS signaling
in these environments; ad-hoc networking, and service provision in ad-hoc networks. The
results achieved during last year showed that integrated approaches to mobility, QoS and
service management can be implemented using IP-based protocols with performance
adequate for 3G interactive services. Some activity has also been done, in cooperation
with the wireless area, in new radio resource allocation mechanisms, targeted to specific
IP traffic.
Signalling protocols for optical burst switching networks - We have analysed the network
performance
of
signaling
protocols,
namely
Just-in-time
(JIT),
Just-enough-time,
Horizon, JumpStart, and JIT+. We are presently comparing the relative performance of
these protocols in ring, chordal ring and mesh networks.
4.3.3.2 Traffic Engineering
Traffic modelling and analysis – An improved traffic model and parameter fitting
procedure, based on Markov modulated Poisson processes, which is able to capture selfsimilarity over a range of time scales, was proposed. This version achieves a much lower
number of states when compared with previous ones. The fitting procedure matches the
complete distribution at each time scale, and not only some of its moments as it is the
case in related proposals. This new version of the traffic model The characterization of
general (non-exponential) ON-OFF sources and their adequacy to model real Internet
traffic data in terms of queuing behavior, was also addressed.
Statistical characterization of Internet traffic – We have analysed Internet traffic using
multivariate statistical analysis techniques. We have identified patterns of similar
behavior by grouping Internet users according to measurements carried out in two
distinct ISPs. The grouping of the users was based on their traffic utilization measured
every half-hour. Cluster analysis was used to identify the relevant Internet usage
profiles. The cluster structure was validated through discriminant analysis.
Congestion control in packet networks – This topic was the subject of a PhD thesis
concluded in 2002 where new algorithms for feedback congestion control were proposed
and analysed; the main achievements during this last year were: (i) the derivation of
stability conditions for the proposed algorithms and, (ii) the proposal and study of
mechanisms for source rate differentiation, supported on the algorithms proposed before,
without increasing complexity in core routers.
88
Traffic performance analysis in wavelength routing networks - The work focused on the
role of network topologies in the traffic performance of wavelength routing networks. We
found that the increase of the nodal degree from 2 to 3 leads to large nodal degree
gains, whereas, the increase of the nodal degree from 4 to 5 leads to small nodal degree
gains. Our results show that degree three and degree four topologies of smallest
diameters are the best candidates for use in the optical core of IP-over-WDM networks.
Design of MPLS over WDM networks - Multiple service network design is being addressed
taking particular attention to both single layer design (MPLS networks) and multi-layer
design (MPLS over WDM networks). On the MPLS layer, network design problems and
solving techniques were studied for large-scale MPLS network design under two routing
approaches, destination based ro uting and source-based routing. This work is being
proposed for publication. On the MPLS over WDM network design, problems were
addressed which are a combined WDM lightpath routing, core LSR placement and LSP
routing aiming to determine the least cost network solution. These problems differ
between them on the design requirements spanning between optical transmission
maximum length, LSP maximum number of hops and fault-tolerance requirements. One
of these problems was already published in IEEE INFOCOM 2003 conference and the
others are being subject to publication.
TCP/IP over HF links - Following a performance study of TCP/IP communications over an
HF point-to-point transmission system done in previous year, further developments were
done in order to implement a communication platform that can interconnect two LANs
with an HF point-to-point link following the military standards STANAG 4539 and 5066.
This platform supports the most important IP services (DNS, HTTP, Email, proxy, Web
caching) optimised to take the most out of the link bandwidth and with the capacity of
service differentiation between the services. This work is being supported by Portuguese
Navy and will be terminated in the first months of next year.
TCP/IP over satellite links - Work addressed the development of a transport architecture
for reliable end-to-end transfer in satellite networks, as an alternative for overcoming the
poor utilization of satellite links that TCP affords in such environments. The work in 2003
included, in the context of the second phase of the ESA TPSAT project, the redesign of
the architecture and protocols developed in Phase 1 of that project, as a result of
changed requirements. Activity was started in the study of long range dependence
properties of traffic generated by polynomial and exponential backoff random access
algorithms.
COST 279 - Support continued to be provided to the coordination of COST Action 279, via
a contract established for that purpose with the European Union. Part of the associated
work involved the preparation of the COST 279 Mid-Term Seminar, to be held in Rome at
89
INSTITUTO
DE
TELECOMUNICAÇÕES
the end of January 2004, and the final editing of the COST 279 Mid-Term Report,
prepared for distribution at the Seminar.
4.3.3.3 Network Operations, Management and Planning
Network security using software agents - We are developing an agent-based approach for
detection and notification of security vulnerabilities in TCP/IP hosts. The software agents
under development are to be FIPA-compliant and will allow an intelligent and dynamic
detection of security vulnerabilities.
QoS Management - IT has contributed to the specification and development of an API for
Service Quality Management (SQM), within the OSS/J initiative. We specified and
developed a prototype for the end-to-end QoS management of IP Networks (SQM v1.0, )
and defined a lab setup to carry out the related experimentations. We also carried out
experiments of the IPTEL SER open-source platform, with special focus on trigger
programming for Service Provisoning, using CPL (Call Processing Language).
Techno-Economic Analysis of Networks and Services - This thematic area of research is
devoted to the study of the technological, economic and financial aspects associated with
the
provision
of
telecommunications
networks
and
services.
The
research
has
encompassed a variety of issues that include socio-territorial factors (regional topology,
demography, socio-economic patterns, available networks and other infrastructures),
technological issues (candidate network solutions, candidate service offers), regulatory
framework and business models.
4.3.3.4 Impact of Telecommunications in Society
Telecommunications and Society - This thematic area of research is devoted to the study
of the effects of emergent information and communication technologies and services (in
particular telematic services such as Internet) upon different sectors of human and
organizational activity. In addition, the role of telematic services and networks as basic
preconditions for the efficiency of modern productive systems and catalizers of social and
economic development is also addressed.
4.3.3.5 Processing, Analysis and Coding of Audio and Visual Information
Object-based rate control – The research activity in this area has continued to address
the development of rate control solutions for video scenes represented as a composition
of objects such as adopted by the MPEG-4 standard. During 2003, the major
90
achievement has been the study of the best rate and distortion models in the context of
object-based MPEG-4 video encoding by comparing different rate and distortion models
for Intra and Inter coding in the form of rate-quantization, distortion-quantization and
rate-distortion functions.
Object-based error resilience – We have continued to address the problem of maximizing
the video quality when transmitting object-based video data through error prone
channels. During 2003, the major achievements have been: 1) the development of a
technique to conceal shape errors in the binary alpha planes or in the binary supports of
gray scale alpha shapes corresponding to the objects in object-based image or video
coding systems such as MPEG-4; this assumes that most contour segments are rather
smooth and uses Bézier curves to interpolate them; 2) the development of a temporal
technique to conceal shape errors in binary alpha planes or in the binary supports of gray
scale shapes corresponding to the objects; to conceal the corrupted shape, the decoder
starts by assuming that the alpha plane changes in consecutive time instants can be
described by a global motion model; then, since not all alpha plane changes can be
perfectly described by global motion, an additional local motion refinement is applied to
deal with areas of the object that have significant motion.
Video coding with fine granularity scalability – During 2003, the major achievement in
this area has been the development of a H.264/AVC based fine grain scalable video
encoder which also exploits the motion compensation tools of the H.264/AVC standard to
take benefit of the temporal redundancy in the enhancement layer which is predicted
from a high quality reference obtained from past information from the enhancement and
base layers; moreover drift reduction techniques are proposed to limit the negative
impact on the quality when part of the enhancement layer used for prediction is not
received by the decoder.
Face detection and recognition – Research in this area has been developed in
collaboration with the Philips Laboratories in The Netherlands and has targeted the
design of facial detection and tracking algorithms in the DCT compressed domain; a low
complexity algorithm has been developed, able to perform in real-time in resourceconstrained environments such as mobile terminals.
Extraction of text from video – Since the creation of content descriptions with high
semantic value has become an important issue, this activity targeted the development of
an algorithm able to perform the fully automatic extraction of natural and synthetic text
from images and video, in the later case exploiting the temporal redundancy.
Video Segmentation - Algorithmic development has focused on surveillance applications,
using completely automatic segmentation techniques that estimate the camera noise and
then automatically select the most appropriate threshold for separating moving from
static regions. Also an automatically adjustable object memory is included to handle
91
INSTITUTO
DE
TELECOMUNICAÇÕES
situations when (parts of) the objects temporarily stop moving. This segmentation
solution has been developed in the context of the integrated segmentation framework
previously developed, by selecting the most appropriate techniques available that
correspond to the segmentation scenario in which this application fits. The work on
objective video segmentation quality evaluation has also continued and it has been
applied to compare the adequacy of different candidate video segmentation algorithms
for a given application.
Video description - The application of video descriptions, which are extracted once from a
given video and stored in a standard format (MPEG-7), has been considered. In
particular, there has been work related to the usage of these descriptions for video
summarization. Also the application of video description for video genre classification
applications has been started.
Image Restoration – Work on wavelet-based image restoration has been further pursued.
We were able to develop iterative deconvolution algorithms, with provable monotonity
properties, which, unlike previous methods, can be used with shift invariant wavelet
bases. These new algorithms achieve state-of-the-art performance on benchmark
problems. During 2003, we have also worked towards extending this type of approach to
problems of blind deconvolution and of super-resolution.
Still Image Compression – Here, basic research on the use of independent component
analysis (ICA) for image compression has been carried out. Since the
bases obtained
with ICA are non-orthogonal, two methods were considered to obtain the image
representations: matching pursuit type algorithms and orthogonalization of the ICA bases
followed by standard orthogonal projection. Our main conclusions were: bases learned
from natural images generalize well to other classes of images; bases learned from the
other specific classes show good specialization. For example, for fingerprint images, our
coders perform close to the special-purpose WSQ coder developed by the FBI. For some
image classes, the visual quality of the images obtained with our coders is similar to that
obtained by JPEG2000, which is currently the state of the art still image coder.
4.3.3.6 Pattern Recognition and Automatic Learning
Unsupervised Learning - New clustering algorithms and partition combination techniques
were given special attention, leading to original theoretical and algorithmic contributions.
Work was also done on the topic of feature selection for unsupervised learning; in this
topic, two types of methods were developed, one extending the classical “wrapper”
approach, used in supervised learning, to the unsupervised case, the other by defining
the concept of “feature saliency”, a quantity that we have shown that can be estimated
by an expectation-maximization algorithm.
92
Supervised Learning – The Bayesian techniques for learning sparse classifier that have
been develop in 2002 were extended
in several directions: inclusion of feature
scaling/selection in kernel-based classifiers; multi-class formulations, by moving from a
“probit” to a “logistic” formulation; development of faster bound-optimization algorithms,
both parallel and sequential.
Tutoring systems - Here, under a Bayesian learning approach, the personal identification
problem was addressed, in the context of the work developed by a PhD student.
Multimedia Databases – In this area, we are developing indexing and retrieval tools
based on information distances (of the Kullback-Leibler type), both in a classical
(Shannon) information theory context and in a computational (Kolmogorov) information
theory framework. These approaches will allow developing “agnostic” measures (for
example, of similarity), in the sense they they do not rely on any explicit probabilistic
modelling and are theoretically universal.
4.3.3.7 Speech analysis and recognition
A main topic of research was the study and the implementation of a method to perform
word confidence measures in an automatic speech recognition system. The confidence
measure is computed during the decoding phase and is based on likelihood ratios
between the top hypotheses that reach a word node. Experiments were carried out on a
digit database with a connected-digit recognizer. This efficient method can be applied
with advantage in small or medium vocabulary recognizers, with low computational
resources. The digit recognizer was also integrated in the Windows Sapi environment.
Another research topic was the study of a speech coder for very low bandwidth
communication channels, with significance analysis of its parameters. A new addressed
topic is the analysis of plosive sounds to enhance the speech perception of cochlear
implanted persons. Also, a study of phoneme recognition with neural networks has been
initiated.

Euro-NGI is a Network of Excellence from the Sixth Framework
Programme, Priority 2, Information Society Technologies (IST), of the
European Community. The main objective of the Euro NGI network is to
create and maintain the most prominent European center of excellence
in Next Generation Internet design and engineering, acting as a
“Collective Intelligence Think Tank”, representing a major support for
the European Information Society industry and leading towards a
European leadership in this domain. The recent technological advances
will lead to exploitable innovative services once the integration of these
technologies through innovative architectures is achieved. The Next
Generation Internet (NGI) will offer view multi-service/multimedia,
mobility, convergence (services and fixed- mobile), Quality-of-Service
and variable connectivity as the norm. On one hand, future high-speed
wire-line and wireless access technologies provide instant high
bandwidth connectivity, which makes difficult to forecast traffic and
thus to apply existing traffic engineering methods. On the other hand,
the technology diversity explodes and mastering such a heterogeneous
environment becomes essential to the network designer. This requires
investigation into new multi-technology architectures. It is understood
today that new design, planning, dimensioning and management
principles are needed. In this context, the main topics addressed by the
NoE are: - Mastering the technology diversity (vertical and horizontal
integration) for the design of efficient and flexible NGI architectures. Providing required innovative traffic engineering architectures adapted
to the new requirements and developing the corresponding appropriate
quantitative methods. The network experts bring the required
competences on the various technologies that will be integrated. They
also bring a worldwide recognize expertise on the various topics that
composes the traffic engineering and optimal dimensioning domain.
Due to the wealth of technologies and tools, achieving the above cited
objectives requires the integration of European research capacities to
reach a critical mass.

The main objective of this project is to improve the capabilities of
networked systems to detect possible security flaws by using Agentbased applications. The main aim is to enable the dynamic, intelligent
and autonomous detection of vulnerabilities and exposures in systems
and to make them available to network administrators. We will use
FIPA-compliant Agents to monitor the network and interact using ACL
(Agent communication language). There are two main advantages of
this approach: we will reduce the amount of data send to network
administrators (currently used tools send huge amounts of data), and
present only relevant information preprocessed by our agent. The other
advantage is the ability of knowledge interchange between Network
Agents and User Agents, which by it self can bring a natural
enhancement to the overall performance of the system.

SCALE II / POSI/42069/CPS/2001
Trafic Modelling and Performance Evaluation of Multiservice Networks
This project aims at proposing the adoption of traffic models based on
real traffic traces to support the design and management of the future
Internet. The project will initially extend the work initiated in the SCALE
project to develop fitting procedures for MMPPs, through the proposal
and implementation of procedures to fit Batch Markovian Arrival
Processes and Markov Modulated Compound Poisson Processes. These
processes are able to reproduce accurately the first-order statistics and
the autocovariance structure for the time scales of interest, so as to
describe appropriately the long-range dependence characteristics that
are common in observed traffic. Other processes exhibiting these
properties will also be explored, e.g., the autoregressive process with
Markov regime. Overall, the model fitting activities will be constrained
by the need to match the traffic characteristics that have more impact
in network performance, within the time scales of interest. The impact
of splitting the traffic in classes according to its statistical properties is
also investigated by extracting models for each individual class from the
aggragate traffic data and studying their interdependencies.

The approach followed exploits the ideas of supporting the end-to-end
concatenation of arbitrary transport protocols, and of providing and
exploiting mechanisms for applications exchange information with a
satellite resource manager about their resource requirements. The
scope of the project comprises the development and validation of a
transport and resource management architecture and of a transport
protocol adapted to the satellite link environment, and the
implementation and test of a prototype.

TPSAT2
Transport Protocol and Resource Management for Mobile Satellite Networks
- Phase 2
Description
In this project is developed a transport architecture for reliable end-to-end
transfer in satellite networks, as an alternative for overcoming the poor
utilisation of satellite links that TCP affords in such environments. The
approach followed exploits the ideas of supporting the end-to-end
concatenation of arbitrary transport protocols, and of providing and
exploiting mechanisms for applications exchange information with a
satellite resource manager about their resource requirements. The scope of
the current 2nd phase of project TPSAT is the redefinition of the
architecture developed in Phase 1 to a scenario of interconnection of LANs
in a fashion transparent to end user applications and implementation and
test of a prototype.

4.4.3.1 Technology and Materials
Some new developments in the preparation of electroluminescent polymers with
regulated solubility for the fabrication of patterned structures of the micron to nanoscale, with potential applications in multi-color displays, integrated electronics and smart
photonic structures, have been achieved.
A contribution has been made, by providing the suitable polymer, to the development of
nanostructures of an electroluminescent organic polymer with a lattice constant of 333
nm via direct scanning near-field lithography.
A new soluble electroluminescent polymer was synthesized which, in solid film obtained
from a solution, becomes completely insoluble upon brief (10 seconds) UV irradiation,
while the luminescence properties are maintained. Compared to the polymer firstly
applied in the fabrication of nanostrutures, this new material carries on remarkable
advantages related to higher chemical stability and easier processing.
Strategies for improvement of light-emitting diodes have been developed, either by
optimization of self-aligned processes or by preparation of adequate polymers for
patterned structures.
Collaboration with the University College London has been established in order to
fabricate nanometer-size structures by near-field optical microscope assisted lithography
using a precursor-form of a luminescent polymer and to prepare a new polymer able to
undergo a similar processing.
Studies of perylene-based molecular conductors under high magnetic fields have been
initiated. The involvement of this group at IT was focused mainly on EPR studies of new
synthesized compounds, either as final materials or precursor entities for the building up
of molecular conducting materials.
4.4.3.2 Integrated Circuits and Systems
There are two distinct lines of work in this sub-area:
•
Design Automation
•
Electronic Systems Design
130
The former of these two can be further subdivided into the following lines of research:
o
development of design automation tools for “System-on-Chip” applications
o
development of E-Design/E-Learning environments to support collaborative
design activities
For the first of these, the tools are: i) circuit and system optimization techniques,
particularly the use of modified genetic algorithms applied to a broad range of circuits
and systems; ii) automatic circuit and systems topology search based on evolutionary
computation methodologies; and, iii) symbolic analysis and synthesis for analog and
mixed signal systems. For the latter line, i) web/data mining techniques, and, ii)
partnerships with distance learning research teams.
Electronic Systems Design can be split into the following tasks: i) timing issues, namely
clock generation and distribution; ii) high-performance systems, namely front-ends for
optical communications, both in CMOS and low-cost GaAs; and, iii) architectures for
network systems, namely for QoS.
4.4.3.3 Instrumentation and Measurement
Work in the wide field of Instrumentation and Measurement can be further subdivided in
the following topics:
•
ADC characterization and testing;
•
Smart sensors;
•
Telemetry and control;
•
Signal processing applied to sensors and instrumentation.
In what concerns the first of these topics, new models were developed for ADC
characterization and on their basis a new method for the analysis of dual-tone signal
behavior in the phase plane was derived. The standard histogram method was also
studied in terms of error and precision, and a novel quasi-static test method was
proposed.
A large amount of work in the field of use and integration of sensors in multi-sensor
systems was performed, with an application to water quality measurements in mind. In
this
line
of
work,
characterization
of
static
and
dynamic
behavior
of
several
electrochemical sensors was performed. A virtual Network Capable Application Processor
(NCAP) was developed on a PC platform, in order to characterize the analog and digital
131

TELECOMUNICAÇÕES
channels of a Smart Transducer Interface Module (STIM) prototype. This work also
included the interface that enables communication between the two units.
Environmental studies also included the design and implementation of self-organizing
maps for the analysis and classification of data in river water quality on-line monitoring
system, and the design and implementation of an absorbance meter based on colored
light-to-voltage converters.
A distributed measurement system was developed to enable the monitoring of the RF
spectrum for ANACOM-Azores. This involves several types of automatic measurements in
the HF, VHF and UHF bands, as well as remote control of antennas in the relevant
frequency ranges.
Signal processing provided the background for these activities. Sine-fitting techniques
have been developed for application in multiple channel acquisition systems where
physical constrains exist. These numerical techniques have been applied to impedance
measurement where they can reduce the final uncertainty of the impedance estimated
parameters.
Wavelet-based
processing
algorithms
were
developed
for
transient
modulation of the cardiac autonomic system.
4.4.3.4 Power Electronics
In the sub-area that comes under this general heading (but also including some work in
electrical machines and power transformers) the following lines of work may be
identified:
•
High frequency soft switching converters: study, development, theoretical analysis
and simulation of zero voltage switching DC-DC converters. Simulation of
alternative energy storage topologies. Study of alternative converter topologies.
Additional studies on applications on those topology developments, namely
application in switching audio amplifiers and power active filters.
•
Active power filters: Optimization of standard topologies and control processes for
power active filters.
•
Power audio amplifiers: Development of new circuit topologies and control
processes for switch mode audio power amplifiers.
•
Contactless energy transmission Theoretical analysis, simulation and design
optimization of resonant converters working as interfaces for inductive coupling in
order to be used as a contactless power interface. The main objective of this work
is to show the performance of the power stages when operating with a non-ideal
132
transformer, identifying the most important changes in converter characteristics
due to the nonidealities.
•
Electromechatronics: studies in fault analysis, diagnostics and fault tolerance of
electrical machines, transformers, power electronics and other special application
machines. Attention has been also drawn to the maintenance aspects, specifically
related to the telecommunications power supply systems, namely for switchedmode
power
supplies.
Concurrently,
topics
related
to
the
maintenance
management and organization activities, in general, have been considered.
•
Power Quality, electronic ballasts, simulation of transformers.
4.4.3.5 Applied Mathematics
In the sub-area of Applied Mathematics, aside from theoretical studies and collaboration
with fields of research other than Telecommunications, the following general subjects can
be identified:
•
Optimization
•
Numerical Linear Algebra
•
Partial Differential Equations
Specific topics include, not exclusively, the following:
1. Numerical Linear Algebra: Preconditioning and convergence of iterative methods
for the solution of linear systems of equations.
2. Complementarity problems: design, implementation, convergence analyses and
testing of interior-point algorithms, active-set methods, sequential quadratic
algorithms and enumerative methods.
3. Global Optimization: complementarity algorithms, positive semi-definite and
reformulation-linearization techniques for bilevel programming, quadratic and
bilinear
programming
and
mathematical
programs
with
complementarity
constraints.
4. Discrete Optimization: global optimization algorithms for linear, nonlinear and
complementarity problems with integer variables.
5. Solution of Structured Optimization Models, namely finance portfolio selection
models, network models, eigencomplementarity problems and other engineering
models.
6. Solution of Partial Differential Equations associated with contact problems and
other variational models in engineering.
133

7. Design and solution of models of filtering and other areas in telecommunications.
8. Numerical Linear Algebra: preconditioning techniques for the solution of linear
systems of equations.
9. Work has been completed on Computation of the Drazin inverse of a matrix over
an arbitrary ring.
10. Studies of Von Neumann regularity of Bezoutian and Sylvester matrices with
elements in a ring and its application to polynomial theory have been initiated.
11. Work on the characterization of the dispersion profile in soliton links with
dispersion-varying compensating fiber was continued.
12. Iterative methods for large linear systems. A comparison between the explicit
Group AOR method and the point AOR method was done for the model problem,
which shows the computational advantages of this new technique. The interval
version of a new iterative method was presented and some convergence
conditions obtained.

Gels with innovative optical, magnetic and electrochemical properties
The ma in goal of the project is the study of relevant physical properties
of new hybrid xerogels (doped with lanthanide or ferromagnetic ions).
Those sol-gel derived materials, based on oxyethylene units grafted
onto silica networks by urea and urethane cross-links, are efficient
white light emitters due to the convolution of a long-lived emission
originated in the NH groups of the urea or urethane bridges with
shorter-lived electron-hole recombinations occurring in the nanometersized siliceous clusters. This feature will be exploited to obtain efficient
white-light hybrids.
AQA/PNAT/1999/EEI/15 052/C
Global Monitoring Based on Smart Sensors for Environment Quality
The main objective and original contribution of this project is the study,
design and implementation of intelligent automated measurement
systems for the continuous monitoring of parameters considered
important for the environment quality. These systems include smart
cells (i.e. smart sensors or smart actuators) for some physical
quantities with digital processing structures with prediction capabilities.
As new intelligent techniques that will be developed within the project it
should be underlined: ·The sensor fusion and integration that combine
the information in a way that removes inconsistencies and presents
clearly the best interpretation of readings input from many individual
sources. ·Neural and neuro-fuzzy information processing that includes
linearisation, prediction and the correction of sensor characteristics.
Another direction of work will be the establishment of a client-server
architecture linked through a computer network for distributed
measurement systems. The client performs the continuous monitoring
of the electrical signals related to the quantities to be measured and
their transmission to the server database. For the water quantities the
transmission is via the Global Standard for Mobile telecommunication
(GSM) and a Global Position Sensor (GPS) is used for sensors position
detection.

The purpose of this project is to automate the measuring procedures
used in the different Monitoring Centers of ANACOM (Portuguese
Telecommunications Regulator) to monitor and control the
radiofrequency spectrum in Portuguese territory. The automation must
allow remote operation, that is to say, to perform tests for instance in
Azores from another Center, namely the main one sited in Barcarena.
NMMADC/POCTI/ESE/32698/99
New measurements methods in Analog to Digital Converters testing
Phase plane domain model of the ADC behavior will be explored and
presented. This model will include frequency dependent phenomena as
dynamic hysteresis. A procedure aiming at characterizing the ADC
behavior on the phase plane domain will also be developed. The
characterization method will resort to dual tone input signal and Fourier
Transform based analyses of the output.
OCAP/POCTI/ESE/41554/2001
Optimization of Circuit topologies for Active Power filters
Active Power Filters is an important research domain of power
electronics, related with power quality. The main drawbacks of power
filters are: - high acquisition cost for the user, with moderate benefits
to the user plant; the main benefits come to the mains network and
power distribution company - electromagnetic compatibility problems,
name ly those related with radio frequency conducted noise The project
objective is the reduction of the systems cost and the increase of
valuable functions to the user plant, namely including in the power filter
some of the functions usually associated to the power conditioners. The
use of soft switching power converters associated with adequate
modulation techniques would reduce de EMC problems.
SWITCH
