1. Introdução
O Instituto de Telecomunicações (IT) é uma instituição privada sem fins lucrativos,
de utilidade pública, resultante da associação de quatro instituições com experiência e
tradições de investigação e desenvolvimento no sector das Telecomunicações:
•
•
•
•
Instituto Superior Técnico (IST),
Universidade de Aveiro (UA),
Faculdade de Ciências e Tecnologia da Universidade de Coimbra (FCTUC),
Portugal Telecom, através da “Portugal Telecom Inovação” (PTI), ex “Centro de
Estudos de Telecomunicações” (CET).
O IT está organizado em três Pólos: um em Aveiro, no Campus Universitário da
Universidade de Aveiro (UA), outro em Coimbra, no Pólo II da Universidade de
Coimbra (UC) e o terceiro em Lisboa, no IST.
A constituição do IT beneficiou do apoio do programa CIENCIA, num montante total
de 1,5 milhões de contos, através de três contratos celebrados em 1991, com as instituições associadas. Este financiamento permitiu a construção de infra-estruturas nos
três Pólos e a aquisição de equipamentos para os respectivos laboratórios.
A instalação do Pólo de Aveiro ficou concluída em 1993 e a dos pólos de Lisboa e de
Coimbra em 1994. Nesse sentido pode-se considerar que, desde 1995, o IT desenvolve uma actividade em regime normal. Resumem-se, em seguida, algumas das actividades mais marcantes realizadas em 2000 deixando para os relatórios das linhas de investigação o seu desenvolvimento.
2. Organização interna
A gestão do IT é essencialmente descentralizada nos Pólos. A gestão de cada Pólo goza de ampla autonomia para a gestão corrente. A Comissão Executiva e os membros
das Comissões de Gestão dos Pólos reúnem-se pelo menos uma vez por mês.
O Conselho Científico reúne-se duas vezes por ano, para apreciar num caso o Plano
de Actividades e o Orçamento e noutro o Relatório de Actividades, bem como qualquer assunto que lhe seja proposto pela Comissão Executiva. O Plano de Actividades
e o Orçamento, por um lado, e o Relatório de Actividades e Contas (depois de certificadas) por outro, são seguidamente submetidos à Assembleia Geral para aprovação.
Tanto o Plano de Actividades como o Relatório de Actividades são discutidos e comentados com a Comissão de Aconselhamento.

No ano de 2000 realizaram-se as seguintes reuniões:
•
•
•
•
duas Assembleias Gerais, uma em Março, em Lisboa, para aprovar o Relatório de
Actividades e Contas de 1999 e outra em Dezembro, em Lisboa, para aprovar o
“Plano de Actividades e Orçamento para 2001”;
reuniões mensais da Comissão Executiva;
uma reunião com a Comissão de Aconselhamento, formada por três especialistas
no domínio das telecomunicações (Dr. Roland Hüber, Prof. John O’Reilly e Prof.
Martin Tomlinson) actuando a título pessoal que, em Junho, visitaram o Pólo de
Lisboa, apreciaram detalhadamente as actividades do IT em 1999 e as propostas
para 2000 e formularam recomendações para actividades futuras;
duas reuniões do Conselho Científico, uma em Março, em Lisboa, para discutir o
“Relatório de Actividades de 1999", e outra em Dezembro, em Aveiro, para preparação da proposta de “Plano de Actividades para 2001” a submeter à Assembleia Geral em Dezembro de 2000 e para continuar a discussão do documento de
Planeamento Estratégico do IT com particular incidência na organização interna.
Em meados de Dezembro foi recebida uma primeira resposta da Fundação para a
Ciência e Tecnologia (FCT) à candidatura do IT a laboratório associado que deverá
ser negociada em 2001.
Tal como previsto, no ano de 2000 e em parte já em 2001, continuou a discussão sobre a Revisão Estratégica, com o objectivo de alcançar um novo esquema de organização interna, mais bem adaptado ao ambiente interno do IT e, ao mesmo tempo, susceptível de projectar uma imagem mais coerente do IT e das suas actividades. Assim
foram definidas três temáticas transdisciplinares que definem e caracterizam a actividade do IT:
•
•
•
Comunicações móveis,
Comunicações ópticas,
Redes e Comunicações Multimédia,
às quais acresce uma área horizontal de Ciências Básicas (Matemática e Física Aplicadas e Teoria da Comunicação) e de Tecnologias de Suporte das Telecomunicações
(Electrónica e Instrumentação e Medidas).
Esta decisão, pelo facto de ter sido tomada em finais de 2000, não transparece ainda
deste relatório de actividades.

3. Projectos de âmbito nacional
Durante 2000 estiveram activos 30 projectos financiados pela FCT, no âmbito do
programa PRAXIS XXI, dos quais 2 envolvendo mais de um Pólo.
Na sequência do concurso para projectos financiados pela FCT, com termo em Janeiro de 2000, foram seleccionados, para financiamento, 15 projectos apresentados por
equipas do IT, dos quais 9 se iniciaram ainda em 2000. Destes 15 projectos, 10
envolvem o Pólo de Lisboa, 3 o Pólo de Aveiro, 1 o Pólo de Coimbra e 1 os Pólos de
Aveiro e Lisboa.
No Pólo de Aveiro, sob contrato com a Portugal Telecom (PT) decorreu actividade
em 11 projectos nas áreas de redes e comunicações integradas (7), rádio, microondas
e ondas milimétricas (1) e componentes ópticos e opto-electrónicos (3). O Pólo de
Lisboa, esteve também envolvido em 2 projectos por contrato com a PT .
A diminuição, muito significativa e infelizmente continuada, das encomendas da PT,
que afecta especialmente o Pólo de Aveiro, influiu negativamente nos resultados deste exercício. Até ao momento, porém, uma gestão prudente tem permitido que esta
situação não afecte negativamente o normal funcionamento do IT.
Continuou a verificar-se uma dependência, a nosso ver excessiva, num pequeno número de fontes de financiamento, das quais duas, a FCT e a PT, representam cerca de
90 % do montante total. Esta situação merece uma acção determinada no sentido de
encontrar fontes alternativas de financiamento.
Depois de prolongados esforços junto da FCT e do IST foi finalmente possível, no
início de 2001, conseguir a transferência para o IT do financiamento plurianual
atribuído pela FCT ao IT-Lisboa que, até finais de 2000, foi geridos pelo IST. Esta
nova situação, com reflexos apenas no exercício de 2001, permite uma maior
agilidade na movimentação dos fundos e uma maior transparência na sua
contabilização.
4. Projectos comunitários
A participação do IT em projectos comunitários de I&D, em particular no programa
ACTS (4º Programa Quadro da União Europeia) e no programa IST, decorreu no
âmbito dos seguintes projectos:
•
•
•
TERA, no domínio dos resultados técnico-económicos do programa ACTS;
DIFFERENCE, em arquitectura de redes;
SAMBA, em comunicações móveis de banda larga em ondas milimétricas;
7
•
•
•
•
•
DICEMAN, em codificação de imagem (MPEG-7);
ATLAS, em transmissão óptica;
BRAHMS, em transmissão de banda larga via satélite;
SHUFFLE, em redes UMTS;
ASILUM, em sistemas UMTS.
Destes os primeiros 4 são continuação de projectos iniciados em exercícios anteriores
e chegaram ao seu termo. Os restantes 4 são novos projectos, do Programa IST.
A maioria destes projectos envolveram equipas de um único pólo: Lisboa, no caso do
DICEMAN e do BRAHMS e Aveiro, no caso do DIFFERENCE, TERA, ATLAS e
SHUFFLE. O projecto SAMBA inclui equipas dos Pólos de Aveiro e Lisboa.
Equipas do IT participaram nos projectos COST 252, 255, 257, 259, 260 e 262.
Alguns dos projectos a que se faz referência neste relatório foram desenvolvidos em
colaboração com as instituições associadas.
5. Prémios
José Carlos Pedro e Nuno Borges de Carvalho receberam o 2000 IEE (Institution of
Electrical Engineers) Measurement Prize pelo seu trabalho “Multi-Tone Intermodulation Distortion Performance of 3rd Order Microwave Circuits”.

Após um período (1994 –1998) de crescimento muito rápido a produtividade científica do IT, em termos de publicações, tem-se mantido aproximadamente constante.
Foi o que aconteceu em 1999 e também em 2000. Esta situação deve-se sobretudo à
falta de novos alunos de doutoramento que, com a situação do mercado de emprego
do sector das telecomunicações, tem sido quase impossível recrutar em Portugal.
Um outro aspecto a que importa fazer referência diz respeito ao reduzido número de
teses de doutoramento concluídas ou submetidas face ao número de estudantes de
doutoramento. Trata-se de um aspecto preocupante que tem merecido a atenção do
Conselho Científico. Tanto quanto foi possível apurar esta situação prende-se com o
facto de um número significativo dos actuais alunos de doutoramento serem docentes
de instituições de ensino superior não universitária aos quais não são nem exigidos
prazos apertados para a conclusão do doutoramento nem concedidas dispensa de
serviço docente e que portanto tendem a prolongar o período necessário para
elaboração da tese por 6, 7 e mais anos.
Uma situação semelhante, embora muito menos grave, existiu a nível do mestrado.
Este assunto tem vindo a ser atentamente acompanhado e evoluiu favoravelmente em
2000.

7. Conferências e Seminários
A série de seminários temáticos do IT , abertos a toda a comunidade científica nacional, foi continuada com três seminários: o primeiro sobre "Televisão Digital" decorreu
em Aveiro, em 21 de Janeiro de 2000, com uma segunda edição em 5 de Julho, em
Lisboa (no anfiteatro da Ordem dos Engenheiros), o segundo sobre "Redes Ópticas
Multigigabit", em Aveiro, em 28 de Junho de 2000 e o terceiro sobre "Optimização"
decorreu, em Coimbra, em 27 de Setembro de 2000. As apresentações têm vindo a ser
disponibilizadas no "site" do Pólo de Coimbra.
O Pólo de Lisboa do IT, em conjunto com o Instituto Superior Técnico, organizou a
Conferência BIANISOTROPICS 2000 - 8th International Conference on Electromagnetics of Complex Media, que teve lugar no Centro de Congressos do IST, de 27
a 29 de Setembro de 2000 e contou com a presença de 77 participantes de 21 países.
Todo o IT, mas com particular impacto o Pólo de Coimbra que tem os aspectos
logísticos a seu cargo, esteve envolvido na preparação da ConfTele’2001 - 3ª
Conferência de Telecomunicações, prevista para 23 e 24 de Abril, no Casino da
Figueira da Foz
Foram organizadas diversas reuniões no âmbito dos projectos comunitários e das
Acções de Cooperação COST em que as equipas do IT estão envolvidas.

1. Introduction
“Instituto de Telecomunicações” (IT) is a private, not-for-profit organisation, an
association of four institutions with experience and traditions in research 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” (PT), through its research unit "Portugal Telecom Inovação",
(PTI), ex "Centro de Estudos de Telecomunicações" (CET)
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 IST.
Setting up of IT was the result of a 1.5 billion escudos grant from Programme
CIENCIA, through three contracts signed in 1991. This investment enabled new
infrastructures to be built and research laboratories to be equipped in each site.
Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994.
Since 1995 IT activities proceed regularly. Key developments during 2000 are
sketched below leaving the details for the report of each individual research line.
2. Management
IT management is mostly decentralised by site. Site management enjoys ample
freedom to deal with current affairs. The Executive Board and the members of the site
management commissions that do not belong to the Executive Board meet at least
once a month.
The Scientific Board meets twice a year to comment on the Work Plan and Budget, on
the Annual Report and on any other subjects put forward by the Executive Board. The
Work Plan with the Budget and the Annual Report and Accounts (after legal
certification) are subsequently submitted to the General Assembly for approval.
Both the Work Plan and the Annual Report are discussed with the Advisory
Committee.
During 2000 the following meetings were held:
•
two meetings of the General Assembly one in March, in Lisbon, to approve the
“1999 Annual Report”, and another in December, in Lisbon, to approve the “Plan
and Budget for 2001”;
5
•
monthly meetings of the Executive Board;
•
one meeting with the Advisory Committee, formed by three independent experts
in the field of Telecommunications (Dr. Roland Hüber, Prof. John O’Reilly and
Prof. Martin Tomlinson) acting in a personal capacity who, in June, visited IT, in
Lisbon, carried out a detailed survey of IT activities during 1999 and proposals for
2000, and issued recommendations for future activities;
•
two meetings of the Scientific Board, one in March to discuss the "1999 Annual
Report" and another in December, to discuss the “Plan and Budget for 2001”, to
be submitted to the General Assembly, and to have a further discussion on the
Strategic Review, with a particular emphasis on the internal organisation.
In mid December IT received a first answer from the Fundação para a Ciência e
Tecnologia (FCT) to its proposal to become an Associated Laboratory. It is expected
that this proposal will be discussed and negotiated during 2001.
As foreseen, during 2000 and early 2001, the “Strategic Review” continued to be
discussed in order to achieve an improved internal organisation, better adjusted to the
internal IT environment which at the same time, is capable to project a more coherent
image of IT and its activities. Following we have defined there multidisciplinary
thematic areas:
•
•
•
Mobile communications,
Optical communications,
Networks and Multimedia,
and an horizontal area on Basic Sciences (Applied Mathematics and Physics and
Communications Theory) and Enabling Technologies (Electronics and
Instrumentation and Measurements).
Since this decision was taken in the end of the year 2000 its consequences are not yet
apparent in this Annual Report
3. National Projects
During 2000, 30 projects financed by FCT, under PRAXIS Programme, were active, 2
of them involving teams from two sites.
After a call for proposals issued by FCT, in January 2000, 15 new proposals
submitted by IT teams were selected for funding. Out of these, 9 started in 2000.
From the 15 projects, 10 involve teams from the Lisbon site, 3 from the Aveiro site, 1
from the Coimbra site and 1 from both Aveiro and Lisbon sites.
6
IT-Aveiro on contract with Portugal Telecom (CET), was involved in 11 projects in
the areas of networks and integrated communications (7), radio microwave and
millimetre waves (1), and electronic and optoelectronic components (3). IT-Lisboa,
also on contract with Portugal Telecom (CET), was involved in 2 projects.
A continued and pronounced decrease in the PT orders, affected mainly the Aveiro
site, lead to substantial losses in the year 2000. So far careful and prudent has
prevented these to affect negatively the normal operation at IT.
There is still a marked dependence on a small number of sources of financing, two of
which, FCT and PT, represent about 90 % of all income. This situation requires a
more determined action in order to find out new sources of financing.
After years of efforts and requests, both to FCT and IST, it was accepted that from
2001 onwards, IT-Lisbon 'plurianual' funds (granted by FCT but managed by IST)
will be transferred and managed by IT. This new situation, which will only be
reflected in the 2001 accounts, will enable faster availability and more transparent
accountancy.
4. European Community Projects
IT participation in European Community research and developments projects, namely
in Programme ACTS (European Union 4th Framework Programme) and in
Programme IST included:
•
•
•
•
•
•
•
•
TERA, in the area of techno economic results from ACTS;
DIFFERENCE, in network architecture;
SAMBA, in wide band mobile communications in the millimetre band;
DICEMAN, in image coding (MPEG 7);
ATLAS, in optical transmission;
BRAHMS, in broadband access via satellite;
SHUFFLE, in UMTS networks;
ASILUM, in UMTS link capacity increase.
The first four of these projects begun in previous years and have now reached their
end. The remaining four are new projects in the scope of the IST Programme
Most of these projects involved teams from a single site: Lisbon in the case of
DICEMAN and BRAHMS and Aveiro in the case of DIFFERENCE, TERA, ATLAS
and SHUFFLE. Project SAMBA was jointly carried out by teams of Aveiro and
Lisbon.
7
IT teams participated in the following COST projects: 252, 255, 257, 259, 260 and
262.
Some of the European Community Projects mentioned in this report were carried out
in collaboration with the associates.
5. Awards
The 2000 IEE (Institution of Electrical Engineers) Measurement Prize was awarded to
José Carlos Pedro and Nuno Borges de Carvalho on their work “Multi-Tone Intermodulation Distortion Performance of 3rd Order Microwave Circuits”.

After a period (1994 – 1998) of a very high growth rate IT scientific productivity, as
measured by its publications, has been more or less constant. This is what happened in
1999 and in 2000. We believe that this is due to the lack of new PhD students, which
have been all but impossible to hire, given the job market in the telecommunications
sector in Portugal.
Another aspect that deserved mention is the small number of concluded and submitted
PhD thesis given the number of PhD students. The Scientific Board has dealt
repeatedly with this subject. The situation seems to be due to the fact that a significant
number of PhD students are staff members of polytechnical schools to whom
deadlines are seldom imposed and who hardly ever get leave of absence and thus tend
to prolong the period to finish a PhD thesis for 6, 7 and more years.
A similar, albeit far less serious situation, has existed for M.Sc. Anyway matters have
improved markedly in 2000.
7. Conferences and Seminars
The series of IT thematic seminars, open to the whole scientific community,
continued. Three seminars were held in 2000: the first on "Digital Television" in
Aveiro, on January 21, with a second edition on July 5, in Lisbon (at Ordem dos
Engenheiros), the second on "Multigigabit Optical Networks", in Aveiro, on June 28,
and the third on "Optimisation", in Coimbra, on September 27. Presentations were
made available on the IT-Coimbra Internet site.
IT-Lisbon and IST organised BIANISOTROPICS 2000 - 8th International Conference
on Electromagnetics of Complex Media. This conference was held at IST, from 27 to
29 September 2000, with 77 participants coming from 21 countries.
All IT sites, with particular emphasis on the Coimbra site which in charge of logistics,
have been involved in the preparation of ConfTele’2001 - 3rd Conference on
Telecommunications, foreseen to take place in April 23 and 24, at the Casino Figueira
da Foz.
A number of COST and Community Project meetings in which IT research teams
participated were organised and held.

planar waveguides; (ii) Ω-NRD: Pseudochiral Non-Radiative Dielectric
waveguide. Nonlinear media: (i) Amplification of WDM solitons in erbium-doped
fiber amplifiers; (ii) Soliton switching in multiple-core fiber arrays (Afonso M.
Barbosa, Carlos R. Paiva, António L. Topa).
•
FCT – PRAXIS XXI – 2/2.1/TIT/1562/95 – ISAC Implementation Aspects of a
Mobile Telecommunication Satellite System Payload with Dynamic Channel
Allocation.
The main objective is to put forward a set of suggestions for the implementation
of a satellite payload RF, given its usage in a mobile communications system with
dynamic channel allocation. The activities carried out during 2000 were: (i)
Design/fabrication/test
of
passive
microstrip
patch
arrays;
(ii)
Design/fabrication/test of a hybrid active phase shifters and design of a monolithic
active phase shifter with BiCMOS and CMOS technologies; (iii) Integration of
phase shifters into the arrays; (iv) Test of the active arrays (Custódio Peixeiro,
João Caldinhas Vaz, J. Costa Freire).
•
FCT - PRAXIS XXI - 2/2.1/TIT/1641/95 Compact Range Antenna Measurement
System at Millimetrewaves Using Dielectric Lenses.
The objective of the project is to update the positioning system of the existing
millimetrewave anechoic chamber, to implement a phase retrieval algorithm from
21
amplitude measurements, and develop new system measurement control software.
The positioning system was specified and acquired, and work continued on signal
phase extraction from amplitude measurements (Carlos A. Fernandes, Afonso
Barbosa).
•
FCT – PRAXIS XXI – P/EEI/12256/1998 Design and Optimization of Shielded
Solid Dielectric Horns.
The objective is to develop new feeding strategies of shielded solid dielectric
horns, to improve the operation bandwidth. Extensive simulation studies were
carried out and compared with experimental results to identify the underlying
physical phenomena, and establish design strategies. A paper on this subject will
be presented in ConfTele 2001 - 3rd Conference on Telecommunications (Carlos
A. Fernandes, Carlos Salema).
•
FCT - PRAXIS XXI - P/EEI/12183/1998 Sensors Production for Intelligent
Network Applications.
The objective is to design a RF CMOS Single Chip for Remote Control Systems
(M. João Rosário)
•
FCT – POSI/33379/CPS/2000 – Fiber Solitons: Propagation, Amplification and
Switching.
This project analyzes the transmission and switching of fiber solitons and will
consider three main research areas: (a) WDM soliton transmission with dispersion
management and in-line control; (b) WDM soliton propagation in erbium-doped
fiber amplifiers (EDFA's) and in erbium-doped fiber couplers; (c) soliton
switching in nonlinear fiber couplers. In WDM soliton communication systems it
is necessary to fully understand the combined effect of dispersion management
with in-line soliton transmission control. The amplification of WDM solitons in
erbium-doped fiber couplers may prove more efficient than the most common
amplification using EDFA's. Finally, in nonlinear fiber couplers, it is necessary to
study the problem of soliton switching - especially when multiple-core nonlinear
fiber couplers are considered. Moreover, mismatched two-core nonlinear fiber
couplers - where the group-velocity dispersion is different for each core - may
have an interesting application as logical gates (Carlos R. Paiva, António L.
Topa).
•
FCT – POSI/34860/CPS/2000 - ILENA - Integration of Lenses with Printed Array
Antennas
The objective is to study the integration of printed passive feeds with shaped
dielectric lenses, to produce compact and low-cost beam-shaping antennas. Work
has started on multi-shell lenses, and has progressed into non-uniform continuous
22
refractive index lenses, using artificial media. One paper on complex media will
be presented at ConfTele 2001 - 3rd Conference on Telecommunications, and two
other on lenses and also on complex media were submitted for the 2001 IEEE APS International Symposium (Carlos A. Fernandes, Custódio Peixeiro, Mário
Silveirinha).
•
FCT - POCTI/ESE/1999/34074 - LDMOSCA - Low Distortion RF MOS Circuits
Advances
Development of new models for CMOS and LDMOS transistors and
improvements on existing ones. Implemention of power amplifiers with those
devices, for mobile communications (Maria João Rosário, Nuno Borges de
Carvalho, João Caldinhas Vaz, José Carlos Pedro). To start January 2001.
•
IST-1999-10741-ASILUM: Advanced SIgnal processing schemes for Link
capacity increase in UMTS.
Development of wideband directional channel models for the characterization of
propagation between mobile terminals and base stations, in terms of adaptive
antennas. Collaboration in a measurement campaign held in Germany.
Development of algorithms for adaptive antennas in the specific scenarios of
UMTS (Luís M. Correia).
•
COST 259: Wireless Flexible Personalized Communications
Development of propagation models for outdoor environments in the UHF and
millimeter wavebands: at the UHF band, models have been developed for urban
scenarios and tested in the city of Lisbon for GSM with the collaboration of
TELECEL; the work in the millimeter waveband has been done within the
characterization of the propagation channel, for both the average decay of power
and signal fading. Also some work was done on traffic aspects, especially
concerning its characterization on the time and space domains, and on
optimization of cellular planning, namely by developing algorithms for
minimizing the number of base stations for given quality conditions (Luís M.
Correia).
•
COST 260: Active and Phased Array Antennas.
Design of new type of printed and non-printed antennas and arrays for mobile
communications (Custódio Peixeiro, Carlos Fernandes, Afonso Barbosa)
•
ICP - Co-Site - Study of the Impact of Wind Turbine Power Generators on Radio
Telecommunications.
Analytical models for characterization of the obstruction and scattering produced
by the wind turbine and supporting tower at VHF and UHF were developed and
tested. Measurements using scaled models in anechoic chamber were used for
23
model validation. These models were applied to a test case, and some guidelines
for establishing a clearance zone around a wind turbine were identified. A paper
on this subject will be presented in ConfTele 2001 - 3rd Conference on
Telecommunications, and another in ACES 2001 (Carlos A. Fernandes, Carlos
Salema).
•
Non-linear Pulse Propagation in Erbium Doped Fiber Amplifiers (internal
project).
Soliton amplification in EDFA's: spectral characterization, WDM systems, noise
and equalization using Erbium doped fiber couplers (Afonso M. Barbosa, Carlos
R. Paiva, António L. Topa).
•
Health safety analysis for mobile communication systems (internal project).
Some attention is being devoted to this area, by evaluating the maximum
transmitted power that is possible at the mobile phone for mobile communications
systems, due to limitation imposed by safety considerations. Also the case of
buildings with GSM base stations on top or in the vicinity has been analyzed (Luís
M. Correia).
•
Cellular planning for non-uniform traffic distributions (internal project)
Optimization of cellular planning parameters, like the ratio of division into microand macro-cells and cell radius for both cell types, in the real case of non-uniform
distributions of traffic in city environments. Deployment cost is being considered
as well. These activities are being developed for both GSM and UMTS, as far as
actual systems are concerned; a more theoretical approach is also being done,
addressing the deployment of future Mobile Broadband Systems (Luís M.
Correia).
•
MMICs on Silicon technologies (internal project)
Test of microwave power amplifiers using chip on board technology. Test of a
low noise down converter for GSM (900MHz) specifications using conventional
CMOS technology. (M. João Rosário).
•

ACTS 308 - DICEMAN - Distributed Internet Content Exchange with MPEG-7
and Agent Negotiations (sponsored by the European Commission DG XIII):
Objective: DICEMAN intends to provide a solution to what is probably the single
biggest problem facing the archive content industry and its consumers today.
Content holders have vast quantities of material, which they would like to sell.
Content consumers have a growing need to access and purchase this content.
53
However, today’s business model is primarily based on paper, videotapes and
CDs, and the postal system, making it slow, expensive and cumbersome. In this
era of digital content and global digital networks, it is time a digital solution to
this problem revolutionized the industry. DICEMAN aims to do this by:
• Opening up valuable databases of multimedia content by making them easier
to search, using advanced forms of descriptions and indexing, and advanced
forms of user interfaces
• Enabling the location of the best content for the purpose, both locally and
globally, over electronic networks, using agent-based assistants to users and
provider.
• Enabling the exchange and trading of multimedia content over electronic
networks using standardized interfaces to electronic databases.
Partners: 8 companies, namely IBM (D), INA (F), CSELT (I) and KPN (NL)
Duration: 2 years, starting in May 1998 (end in May 2000).
Note: participation through IST.
IST participation: The activity at IST in 2000 was mainly concentrated on the
development of face detection and tracking tool and the corresponding interactive
editor. The face detection and tracking tool is based on colour and shape. The first
stage consists in a pixel-based colour segmentation algorithm of the HSV colour
space. For this purpose, a study about the skin-colour distribution of faces in
natural images was first performed. The second stage recognises that an ellipse
can approximate the outline of a human face shape in several positions. In this
stage, an algorithm based on the Hough Transform is used to perform ellipse
detection with some shape constraints. The system implemented has been tested
for a wide variety of natural sequences and the experimental results show that the
algorithm is robust to changes of position, size, orientation and number of faces in
an image.
•
54
ISO/MPEG-4 and 7 (no sponsor):
Objective: Research and standardisation of object-based audiovisual
representation and indexing methodologies.
Partners: Hundreds of universities and companies from all over the world.
IST participation: In 2000, IST mainly contributed to:
• Implementation of the MPEG-4 Video profiles and levels
• Evaluation and development of alternatives for the MPEG-4 Video Buffering
Verifier mechanism
• Development and evaluation of MPEG-7 shape description tools
• Identification of MPEG-21 vision and objectives
A few technical contributions have been presented to MPEG regarding the topics
listed above. Moreover F.Pereira was the editor of the MPEG-7 Requirements and
MPEG-7 Interoperability and Conformance documents and chaired the Ad Hoc
Group on MPEG-7 Interoperability and Conformance for some months.

FCT - POSI/35576/CPS/2000 - Dense Wavelength Division Multiplexing
Systems with Optical Dispersion Compensation (DWDM/ODC)
The project focuses on the performance analysis of dense WDM (DWDM)
systems and all-optical transport networks with optical dispersion compensation
(ODC). The work undertaken within the project in year 2000 was the development
of analytical formulation for performance evaluation of optically preamplified
receivers with arbitrary optical filters; comparison of performance in anomalous
and normal propagation regimes of dispersion supported transmission technique.
•
Optical Protection (internal project)
This project was concluded in 2000. Its main objective was to study and
demonstrate the possibility of realizing network functions, such as add-drop
multiplexing and protection in optical domain. During the year 2000 the add-drop
71
multiplexer developed in previous years was used to simulate an optical ring in
order to show the protection capabilities. This ring was also used to transmit SDH
trafic and to study the relationship between the performance measured by the SDH
multiplexer and the performance measured at the optical level.

FCT - PRAXIS XXI - 2/2.1/TIT/1655/95 - Integrated Circuits for High Efficiency
Power Conversion, Using CMOS Technologies, Based on NMOS Devices
A new methodology was developed which enables important improvements in
Smart Power designs using arrays based on a unique NMOS cell type in matrix
arrangements suitable to implement generic functions required by power control
blocks. This design procedure enables low cost semicustom designs and new ICs
79
configuration strategies of easy industrial implementation towards Smart Power
using standard CMOS technologies, in order to: (a) provide cell libraries of
programmable matrix arrangements based on NMOS structures, to implement the
required functions towards power conversion and power amplification, by means
of convenient metal layers interconnections; (b) provide circuit topologies, that
implement required functions, handling high voltages, to control, drive, sense and
protect devices, resorting, exclusively, to NMOS structures; (c) optimise LDSD
and LDD NMOS transistors, increasing breakdown voltage up to 50V, using a
submicron standard CMOS technology, through the use of new devices (GSLDD
and GSLDSD); (d) decrease significantly low series production cost; (e) reduce
turn-around production cycle; and (f) enable the reuse of functional blocks. The
same methodology can also be applied to sophisticated Smart Power technologies,
for fast prototyping. National and International patents are pending.

In this project were studied models for multiservice multirate traffic and models
for multicomponent calls and their application in the study of QoS support in
multiservice networks.
•
Platform for Universal Access to Applications in a University Campus
Environment
In this project was completed the definition of the architecture of a system for
allowing users of portable computers universal access to the applications found in
a University campus environment. The definition of an appropriate middleware
platform for such system and the development of key modules was done. This
project led to an M. Sc. Thesis, and was concluded in 2000.
•
Quality-of-Service over Packet Networks
In this project, routing algorithms for Quality-of-Service (QoS) provision in
packet-switched networks were investigated. A generic characterization of the
QoS paths for which hop-by-hop routing is possible and for which a generalized
85
Dijkstra’s algorithm correctly computes optimal paths has been found. The
characterization is given in terms of an algebra of link and path weights that
satisfy certain properties. The work in this project gives a contribution to
fundamental research on QoS routing, but it also has an application in  and was,
in fact, motivated by  today’s Internet routing architecture, which uses hop-byhop routing and where one of its routing protocols, OSPF, computes paths with
Dijkstra’s algorithm.

FCT - PCTI/ESE/32698/1999 - New Measurement Methods in Analog to Digital
Converters Testing
A new testing method, developed within this project, based on the use of small
triangular waves superimposed to a variable DC level, proved to substitute with
great advantage the traditional static test of Analog to Digital Converters (ADCs).
The work is now in a pre-normative phase and it will be tested in the near future
in different reference Metrological Institutions in Europe and USA. An automatic
measurement procedure was developed for this purpose.

FCT - PRAXIS XXI - P/EEI/14151/1998 – DSP-Based Winding Fault Diagnosis
in Operating Three-Phase Power Transformers
Funded by FCT, the major aim of this project basically comprises the
development of a prototype, able to provide a complete and reliable diagnosis of
118
the operating condition of three-phase power transformers, particularly regarding
the occurrence of winding faults.
For that purpose, a modelling and simulation study was conducted, concerning
either the normal operation or the failure mode behaviour of three-phase power
transformers, in order to provide an evaluation of the suitability of diagnostic
techniques, which can be applied without taking transformers out of service and
which can also provide a fault severity criteria. The experimental validation work
was also already performed.
The on-going activities are mainly related to the prototype hardware and software
development.
•
TELECOMMAINTENANCE
This project is intended to explore adequate strategies for diagnosing the
occurrence of faults in telecommunications power supply systems. The ultimate
purpose is to include the diagnostic routines into the control module, therefore
allowing for the introduction of remedial control strategies soon after failure
occurrence and thereby improving reliability and maintainability. In other words it
is envisaged the development of fault tolerant telecommunications energy
systems.
Outside of the large switching centers, the switch-mode rectifier/charger rules,
since it is ideally suited for the low power requirements and the potentially
harsher environment. In almost all of these type of systems the location is
unmanned; so reliability, fault tolerance, repairability and monitoring are
important.
For that purposes, a modelling and simulation study is being conducted,
concerning either the normal operation or the failure mode behaviour of switchmode power supplies. Based on the analysis of the results to be obtained, the fault
tolerant strategies that can be adopted against a complete system failure will be
evaluated.
•
PQMS – POWER QUALITY MONITORING SYSTEMS
Reliability and quality are requirements which are particularly important for
premium power sources.
This project is related to the development of a software tool that runs under the
Labview™ environment, and which is intended to provide suitable power quality
indices based on the on-line monitoring of the supply quantities (voltages and
currents).
The analysis of the power quality indices, with reference to existing standards,
graphical displays and statistical processing are among the specified outputs of
this recently started project.
119
•
TELEMAINTENANCE
This project is related to the development and implementation of a remote
maintenance system, which is ideally suited for equipments installed at
geographically dispersed locations, usually unmanned.
The work developed so far encompasses the definition of the communications
channels, protocols, data formats, user interface and the development of the
remote unit, in a Labview™ environment.

FCT - PRAXIS XXI - P/EEI/14160/1998 - LinMix – Linearity Studies in Active
Mixers
Two main work areas were addressed in the 1st year of LinMix Project. The first
one was the development of an appropriate nonlinear MESFET model for mixer
distortion calculations. Taking into account the importance of the cold-FET mixer
for highly linear applications, special emphasis was put on the FET’s triode-zone
modelling.
The second area was the development of a microwave nonlinear circuit simulator.
This simulator is an upgrade of one already in use in our group, in which a mixedmode harmonic balance machine now substituted the multi-tone spectral balance
algorithm, previously adopted. The HB algorithm was applied to mixers driven
with multi-tone signals, by utilising two different innovative artificial frequencymapping techniques.
•
FCT - PRAXIS XXI - 2/2.1/TIT/1562/95 - ISAC-Implementation Aspects of a
Mobile Telecommunication Satellite System Payload with Dynamic Channel
Allocation
Under the nonlinear microwave device modelling activities of ISAC, a physical
simulator was concluded and tested. This simulator implements a quasi-static
version of the drift-diffusion model for FET devices, and uses a 2-dimensional
mesh according to the finite-differences formulation. The Poisson and ChargeContinuity equations are solved using a partially coupled method, which is a
variant of the classic Sharfter-Gummel approach. First simulation tests made with
this simulator proved its use, but also showed the amounts of computer time
needed.
Under the activities of highly linear microwave amplifier design, the studies on
modelling and measuring multi-tone distortion were emphasised. A novel cochannel distortion ratio, which does not suffer from the disadvantages discovered
for the NPR standard, was proposed and fully tested. The supporting theory and
the measurement set-up allow the proposal of a new multi-tone distortion
characterisation standard, which suffered already wide publication and the 2000
IEE Measurement Prize.

The project intends to collect data on Earth-Satellite atmospheric propagation path
to study and model ice induced depolarisation, wet and dry scintillation as well as
rain induced fade dynamics. The main work developed consisted on the
specification of the hardware of the propagation receiver, study of beacon
amplitude/phase detection alternatives for a maximum dynamic range and
specification of pre-processing software. Versatile bias removal user-friendly
procedures for crosspolar discrimination as well as clear sky amplitude reference
level estimation were studied. Software development was started.
•
ACTS 204 - SAMBA: System for Advanced Mobile Broadband Applications
Radio propagation simulations using measured antennas radiation patterns

the field trials. These results are being compared with measured data gathered
during field trials. The objective is to further assess the simulation tool validation
as well to study the propagation phenomena faced in MBS deployment. During
this year, more field trials in indoor scenarios were realised, including the test of
handover procedure. A document was produced (Deliverable DE15). Furthermore,
127
techniques for Channel Impulse response measurement in the frequency domain
were identified.
•

CESTA: Statistical characterisation and simulation of ATM traffic
The project started in 1997 and ended in April 2000. The main objective of the
project was the development of a dimensioning tool for ATM networks that
integrates traffic model fitting and selection procedures with optimisation routines
for cost-effective dimensioning and resource management. The main results were:
(i) developments of two software packages, one for traffic analysis and the other
for network design, (ii) development of methods for parameter estimation of ATM
traffic models, (iii) development of methods for rare event simulation, (iv)
formulation and development of optimisation models for several network design
problems, (v) study and development of meta-heuristics based on genetic
algorithms for solving optimisation problems.
•
FCT - PRAXIS XXI - P/EEI/12135/1998 – DOTE: Dimensioning and Resource
Management Optimisation Algorithms for Telecommunications Networks
This project investigates optimisation algorithms and heuristics suitable for
dimensioning and resource management of telecommunications networks. It is a
134
joint project with the Dept. of Statistics and Operations Research, Faculty of
Sciences, University of Lisbon. The activities concentrated on ATM networks: (i)
research of heuristics and meta-heuristics; (ii) dimensioning of hierarchical
networks; (iv) dimensioning for the support of conversational, retrieval and pointmultipoint services.
•
PRIQUAS: Planning of IP Networks supporting Quality of Service
This project studied the impact in network dimensioning of IP QoS technologies
and developed the first version of a dimensioning tool. The following activities
were carried out: (i) study of IntServ and DiffServ architectures, (ii) study of
MPLS technology, (iii) study of QoS routing protocols, (iv) development of
dimensioning tool.
•

DIMIP: Dimensioning of IP Access Networks
The goal of this project is to research IP based access networks supporting QoS
differentiation. During this year the project concentrated on the architectural
aspects, including the definition of network elements, the allocation of functions
to network elements, the signalling protocols and the migration aspects from
current access network technologies.
•
PIGRAF: Graphical User Interface Platform;
PGRAF project investigated most recent knowledge advance in the design of user
interfaces and has built a modular platform, not tied to proprietary solutions, to
support user interfaces in the area of network topological representations. The
main objective for this platform is the support, in a multi-user environment, of
client interfaces with different views, built with Java and made persistent in a
central repository, taking into account as a main concern, network representations
made up with thousands of objects. During 2000 two main results were achieved.
In first one the graphics server was rebuilt on C++ in HP/UX supporting multiuser access to graphical information with persistence based on Oracle database
and with a rules engine supporting status propagation between objects. The second
main result was the client API built on Java 2 and based on JViews library that
135
supports the visual representation of network topology. Those two modules
interact using CORBA with embedded XML. XML was also introduced on
interface between the server and the host system. There were also other significant
results obtained: a guidelines report on graphical user interfaces and the support
provided to other projects using the platform.
•
GESACESSO: Management of Access Networks
The main goal of this project was to perform research studies on management
interface between “NML – Network Management Layer” and “EML – Element
Management Layer”, applied to UMTS Radio Access Networks and focused on:
independence of network equipment providers and full automation of
management processes. The project was based on the analysis of the work done by
“TMF - Telecommunications Management Forum”, on the “Telecommunications
Operations Map - TOM”, and by “3GPP - 3rd Generation Partnership Project”.
The project produced a deliverable that was an input for a M. Sc. Thesis, where
the management architecture, management information models and detailed “IRPs
– Integration Reference Points” for Resource Provisioning, Alarm Management
and Performance Management, were defined.
•

IST-1999-10626 – ATLAS - All-optical Terabit per second Lambda-Shifted
In the ATLAS project fibre-optic WDM transmission over 500-1,000 km with an
aggregate capacity around 1 Tbit/s is investigated by adopting return-to-zero
signal format and the dispersion management technique, without resorting to
intermediate regeneration. Different network architectures using All Optical
Wavelength Converters (AOWC) are currently under investigation. This project
wants to assess the problems encountered when high capacity fibre transmission is
associated with an intermediate AOWC, namely what is the maximum signal
distortion tolerated at the AOWC input and what is the maximum output distortion
tolerated by the further propagation down the rest of the link.

FCT - PRAXIS XXI - 2/2.1/TIT/1573/95 - DAWN - Dynamically Reconfigurable
Optical Network
This project proposes a new architecture for WDM wireless networks, that allows
a dynamical tuning of the network nodes. In this new architecture the optical
signals with different wavelength will be generated in the same node. At each
node the wavelength will be selected by an optical filter.

FCT - PRAXIS XXI - 2/2.1/TIT/1592/95 - GENCLOCK - Architectures for
High-Speed Clock Generation and Synchronization.
During 1998, the project focused on the development of multi-point distribution
systems, with special emphasis on architectural and modeling aspects. New
generic and scaleable clock distribution architectures have been developed, and
jitter modeling has been analyzed for these (and other) distribution approaches
(concluded 9/2000)
