Patent ID: 8526542

Claim:
A diversity receiver configured to receive VSB (vestigial sideband) signals, comprising: a first demodulator configured to receive a first VSB signal and demodulate the first VSB signal to first VSB data; a second demodulator configured to receive a second VSB signal and demodulate the second VSB signal to second VSB data; a path aligner configured to detect starting points of the first VSB data and the second VSB data and synchronizing the first VSB data and the second VSB data; and a dual channel equalizer/decoder configured to repeatedly perform an equalization process for a selected section, the equalization process including filtering each of the first and second VSB data synchronized in a feed-forward manner, mixing the first and second filtered VSB data, and filtering the mixed result in a decision feedback manner, wherein the dual channel equalizer/decoder includes: a TCM (trellis code modulation) decoder configured to decode a data stream generated by the equalization process into a Trellis code; a de-interleaver configured to de-interleave an output of the TCM decoder; a Reed-Solomon decoder configured to process the de-interleaved data stream by a Reed-Solomon algorithm and output the processed data stream as a transmit stream; and a recursive equalizer configured to filter each of the first VSB data and the second VSB data by a feed-forward method, mix the first filtered VSB data and the second filtered VSB data, and filter the mixed result by a feedback method, the recursive equalizer using the output of the TCM decoder as determination values for the feed-forward filtering and the feedback filtering.
