primary objective of the project is to develop computer algorithms
for certain types of hard discrete problems. The problems considered
are central problems in computer science and any new results in this
area are not only of theoretical but also of practical significance;
applications range from error-correcting codes to analysis of proteins.
Some of the developed algorithms will be released in the form of
general-purpose computer programs. The algorithms will also be applied
to, for example, available biological data.

WomEqual aims at developing operation models for women to support their
career development in business and research institutes, especially in
the field of technology, and at promoting women's innovation activities
and entrepreneurship. A web community of professional women - with
higher educational background, working in the field of technology –
will be created and introduced to support the above mentioned aims.
This web community will provide positive role models for female
students in the field of technology as well as for high school girls
making their future career choices. The web community activities will
combine not only the traditional male and female strengths but also
female interest in co-operation and social networks with the support of
the technology based solutions. Human Factors in Telecommunications

The primary objective of this project is to study algorithms and codes
for error control by mathematical and computational methods. The needs
of modern digital communication systems are taken into consideration in
this basic research project. Iterative coding methods, including LDPC
and turbo codes, play a central role.

Elaboration of signal-processing algorithms for improvement of
bandwidth and power efficiencies of OFDM-based communication systems is
the aim of the project. We assume to elaborate following techniques.
1. Methods of mitigation of harmful impact of nonlinearities, frequency
offsets and subchannels that experience deep fading.
2. Methods of estimation and equalization of nonlinear (including
time-varying) radio channels. The emphasise here will be made on
semi-blind techniques as well as design of pilots.
3. Methods for cancellation of inter-carrier and inter-symbol
interferences with a decreased leaght of the guard interval.
The implementation complexity of the developed techniques is an
important criterion, i.e. we restrict ourselves by practicable

High Capacity Gateway for Emergency
Other researchers: Parviainen, Pekka; Koufos, Konstantinos; Cziner,
DeHiGate is a co-operative project involving European industries and
universities. The project is supported by the CELTIC Initiative. The
overall objectives of the DeHiGate project are to demonstrate a secure
broadband mobile wireless communication system for emergency services
and develop additional units to augment the current systems. The
project will develop a deployable high bandwidth gateway for emergency
services accompanied with applications.

The CHORIST project will propose solutions to increase rapidity and
effectiveness of interventions following natural hazards and industrial
accidents, in order to enhance citizens' safety and communication
between rescue actors. The main objectvie is to develop a system made
of the following subsystems: A fully integrated, reliable and
performing alert chain delivering alerts to authorities with inputs
from heterogeneous sensors, disparate agencies and citizens
Heterogeneous communication means (radio, TV, sirens, GSM) to dispatch
messages from authoroties to as many citizens as possible within the
crisis area with limited delay Secured, rapidly deployable and
interoperable voice and high data-rate telecommunication systems
(including ad-hoc networks) for in the field risk response teams
