Each decoder group includes primary decoding means for decoding the first sequence of codewords in combination with the source sequence of symbols to produce a sequence of primary decoded symbols; intermediate interleaving means for interleaving the sequence of primary decoded symbols using intra-block permutations on the source sequence of symbols and inter-block permutations on each intra-block permuted block across the predetermined number of the intra-block permuted blocks to produce a sequence of intermediate symbols; secondary decoding means for decoding the second sequence of codewords in combination with the sequence of intermediate symbols and a sequence of interleaved source symbols to produce a sequence of secondary decoded symbols; and de-interleaving means for de-interleaving the sequence of secondary decoded symbols to produce a sequence of estimated symbols.

摘要： An equalizer. The equalizer, either operated in a blind mode or a decision directed mode, comprises a feed-forward filter, a feedback filter, a decision device, a control circuit, and a multiplexer. The feed-forward filter receives an input signal. The feedback filter filters an equalized signal. The combiner combines the feed-forward filtered signal and the feedback filtered signal. The decision device maps the combined signal to one symbol of a symbol set. The control circuit receives the combined output and generates a slice control signal. The multiplexer selects the combined signal or the mapped signal as the equalized according to the slice control signal when operated in the blind mode.

摘要： A digital television receiver includes a tuner for down-converting an incoming signal to produce a down-converted signal according to a local oscillator signal corresponding to a selected channel. A filter is coupled to the tuner for filtering the down-converted signal to produce an intermediate frequency (IF) signal. A carrier recovery unit is coupled to the filter for locking to a carrier frequency of the IF signal, and a pre-shift unit is coupled to the tuner. By shifting the local oscillator signal in a first direction by a predetermined first frequency shift in a first phase of carrier recovery, and then by shifting the local oscillator signal in a second direction by a second frequency shift in a second phase of carrier recovery, the pre-shift unit ensures a pilot tone of a selected channel is not filtered from the down-converted signal by the filter.
