ABSTRACT:
Baseband DTV signals are supplied to a cascade filter connection of a transversal filter operative over many data segments and a match filter for data segment synchronizing (DSS) signals. The accumulated random data in the cascade filter response is suppressed by coring, to generate a signal ensemble descriptive of ghosted DSS signal. The transmission channel is characterized based on this ensemble, and the coefficients of a complementary channel-equalization and ghost cancellation filter are calculated based on this characterization.
