Originální abstrakt

The paper deals with the first part of results of the Czech Science Foundation research project that was aimed into the simulation and measurement of the transmission distortions of the digital terrestrial television according to DVB-T/H standards. In this part the modulator performance characteristics and its simulation and laboratory measurements are presented with focus on typical DVB-T/H broadcasting scenario - large SFN network for fixed reception. The paper deals with the COFDM modulator imperfections and I/Q errors influence on the DVB-T/H signals and the related I/Q constellation analysis. Impact of the modulator imperfections on Modulation Error Rate from I/Q constellation and Bit Error Rates before and after Viterbi decoding in DVB-T/H signal decoding are evaluated and discussed
