Originální abstrakt

The contribution deals with the utilization of Matlab for simulation and analysis of digital QPSK and M-QAM modulators and demodulators used in DVB (Digital Video Broadcasting) standard. Presented modulators and demodulators are optional modules of simulation system that can evaluate the influence of transmission errors on transmitted digital signal and according visual information. The system is used for PQ (Picture Quality) and BER (bit-error rate) value valuation during the DVB transmission in RF band. The modulator and demodulator flowcharts are presented including the simulation example. The conclusion outlines the utilization of the modulator and demodulator and approach to transmission channel model in RF band modeling.
