The effects of receiver impairments in terrestrial digital video broadcasting
In this paper, receiver impairments associated with zero intermediate frequency (zero-IF) dual branch receiver architectures are considered in the context of terrestrial digital video broadcasting (DVB-T). The receiver impairments studied are the DC-offset, the gain and phase imbalances, and the frequency offset. Bit error rate simulation is used to observe the influence of first order capacitive coupling for removing DC-offset. Based on the study of gain and phase imbalances, we arrive at values which are required in order to maintain the proper operation of the DVB-T signal. Also, acceptable frequency offset limits for the proper operation of the DVB-T signal are given.
