FEKT-MPC-RKOAcad. year: 2021/2022
The course addresses the theoretical apsects of modern radi 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 and signal space representation. Students get detailed informations about transmission over fading 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.
Learning outcomes of the course unit
The graduate of the course is able to: (a) represent the signal in the signal space; (b) choose a suitable filter for intersymbol interference reduction; (c) discuss the method of Bayesian statistical detector; (d) explain the principles of modulation techniques; (e) create a MATLAB program simulating the principles of digital communication theory; (f) illustrate the structure of OFDM modulator and demodulator; (g) compute the output of a block space-time coder.
The student who registers the course should be able to explain the basic terms from the area of probability and statistics, describe mathematicaly basic analogue and digital modulation techniques, create a simple program in the MATLAB environment, compute the response of linear systems to input, discuss the basic terminology and methods from the signal processing theory
