Combinatorial Algorithms

Project leader: Östergård, Patric
Other researchers: Pottonen, Olli; Seuranen, Esa; Vaskelainen, Vesa
The 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.
Keywords: clique, code, combinatorial algorithm, graph algorithm, matching, optimization, systems biology (EU tutkimusluokitus: P 170 (Computer science, numerical).

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 research group in doing research and development for the web community using user-centered research methods.
Keywords: User-centered design, web community, women in technology

Codes and Algorithms for Error Control in Digital Communications

Project leader: Östergård, Patric
Other researchers: Riihimäki, Vesa; Vaskelainen, Vesa
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.
Keywords: iterative coding, LDPC code, turbo code (P 170 (Computer science, numerical).

Bandwidth and power efficient OFDM-based communication systems

Project leader: Häggman, Sven-Gustav
Other researchers: Ermolova, Natalia
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 algorithms.
Keywords: OFDM, nonlinear effects, frequency offset effects, deep fading

Deployable High Capacity Gateway for Emergency Services (DeHiGate)

Project leader: Jäntti, Riku
Other researchers: Parviainen, Pekka; Koufos, Konstantinos; Cziner, Krisztina

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.
Keywords: public safety, crisis management, gateway, wireless, Ad hoc, network, broadband, deployable
Research programme: CELTIC - A Eureka Cluster Programme to foster European leadership in telecommunications (CELTIC), DeHiGate ( CP2-008).

Integrating Communications for enhanced environmental risk management and citizens safety/Chorist

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
