Abstract

In this article author’s study results in direction of performance analysis of digital terrestrial television broadcasting system in DVB-T and DVB-T2 standards in combined influence of quadrature impairments and AWGN. Main purpose of studies is estimation of technical operational quality degradation in such systems in different conditions of performance non-ideality of quadrature modulator/ demodulator with different relationship between impairments for combined influence. For this the simulation model of DVB-T2 system path providing possibility of quantitative and qualitative estimation of technical operational quality in condition of quadrature impairments and AWGN is implemented in Matlab/ Simulink mathematical modelling environment. As a result quantitative and qualitative estimations of DVB-T rand DVB-T2 performance in condition of combined influence of quadrature impairments, i.e. I/Q amplitude and phase imbalance, and AWGN, with definition of threshold levels of impairments are provided for the first time. Moreover indepth analysis of influence of configuration choice of DVB-T/DVB-T2 systems on acceptable impairment level during appearing of I/Q amplitude and phase imbalance and AWGN are carried out. Derived values can be used for such impairment level fixing and control during technical maintenance, certification tests and starting-up/adjustment work.
