Räisänen, Antti: CoE in Smart Radios and Wireless Research

The CoE conducted high-level research and training in radio science and engineering and wireless telecommunications.

Major areas of research included high-frequency, microwave and millimetre-wave engineering, multi-antenna systems, multi-standard radios, the design of integrated circuits for data communications and signal processing in wireless telecommunications.

Research aims

Areas of research at the CoE ranged from the electromagnetic modelling of man-made materials and telecommunications theory to signal processing algorithms, antenna and circuit design and the development of radio measurement technology and prototype radio systems.

Intelligent multi-antenna systems allow for the more efficient use of the radio spectrum. Intelligent radio sensors and millimetre wave cameras are used among other things to improve the efficiency and safety of passenger and freight transport and the performance of industrial processes.


The CoE was headed by Professor of Radio Engineering Antti Räisänen, who had charge of the Radio Laboratory at Helsinki University of Technology (HUT). Räisänen was then also chair of the Scientific Council for Electrical and Telecommunications Engineering, member of the HUT PhD thesis committee, and board member of the MilliLab research institute, a joint venture between HUT and VTT Finland.

The CoE was based at the HUT Department of Electrical and Communications Engineering and consisted of three research teams in radio technology, one in signal processing and one in electronic circuit design technology. The CoE had a staff of around 90. Some 30 had a PhD degree and around 40 were writing their dissertation.

All research at the CoE was done in close collaboration with the wireless telecommunications and technology industry. The CoE was thus closely involved in developing Finnish society and in maintaining the competitiveness of the national economy.

The unit also had Academy of Finland CoE status during the previous term in 2002–2007.
