  • Abstract
    This paper deals with the modulator imperfections and I/Q errors influence on the DVB-T signal and its spectrum and I/Q constellation analysis. Theoretical backgrounds of the Amplitude Imbalance, Phase Error and Carrier Suppression effects are summarized in the paper. Then the practical results measured in the laboratory environment are compared with the theoretical assumed impacts on Modulation Error Rate from the I/Q constellation and Bit Error Rates before and after Viterbi decoding in DVB-T signal decoding.
