摘要:
Provided is a receiver for processing VSB signal. The receiver includes a first equalizer/decoder unit and a second equalizer/decoder unit. The first equalizer/decoder unit performs a first equalizing operation, first TCM decoding and first RS decoding on a received symbol to output a first dibit. The second equalizer/decoder unit performs a second equalizing operation, second TCM decoding and second RS decoding on the received symbol to output a transport stream. The first dibit is provided as a priori information for a soft-decision operation of the second TCM decoding.
摘要:
A symbol sequence corresponding to a vestigial sideband (VSB) signal is divided into a plurality of sections, respective ones of which correspond to respective time periods. Individual ones of the sections are recursively adaptively equalized to produce respective equalized sections. A bit stream is constructed from the equalized sections.
