Course detail

Wireless Communications

FEKT-GTRKAcad. year: 2018/2019

The course addresses the theoretical apsects of modern radio communication theory. It emphasizes on the comprehension of principles of operation of communication systems. The students improve their knowledge in the area of signal processing applied in communication theory, e.g. the algorithms of signal space representation. Students get detailed informations about transmission over fading channel, transmission using the spread spectrum principle, OFDM technique and MIMO systems. During the practical computer ecxercises, the students verify the theoretical knowledge using the MATLAB computer simulations.
