Realization of a versatile 8-VSB exciter in a single CPLD for multi-purpose digital television applications

In this paper the realization of a complete 8-VSB-exciter in a single CPLD is described. The implementation consists of the complete FEC-encoder as well as the signal processing part, i.e., carrier insertion, VSB-filtering and IQ-modulation. The advantages of this realization and possible applications are shown.
