Title
DVB-T Modulator Imperfections Evaluation and Measurement
Abstract
The paper deals with simulation, evaluation and measurement of the DVB-T modulator imperfections. Modulator imperfections' and I/Q errors' influence on the DVB-T signal and its spectrum and I/Q constellation analysis are presented. Theoretical backgrounds of the Amplitude Imbalance, Phase Error and Carrier Suppression effects are outlined in the paper. Then the practical results measured in the laboratory environment are compared to the theoretical assumed impacts on Modulation Error Rate from I/Q constellation and Bit Error Rates before and after Viterbi decoding in DVB-T signal decoding. Commented results of the measurements are presented in the paper as well.
