Course detail
Wireless Communications
FEKT-MPA-RKOAcad. year: 2024/2025
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 significantly improve their knowledge in the area of signal processing applied in communication theory, e.g. the algorithms of signal detection. Students get detailed informations about transmission over radio channel, transmission using the spread spectrum principle, OFDM technique and about MIMO systems. Moreover the students get knowledge on the advanced coding principles - e.g. the turbo and LDPC codes. During the practical computer ecxercises, the students verify the theoretical knowledge using the MATLAB computer simulations.
