A receiver for providing a corrected output symbol sequence is disclosed. A decision feedback equalizer (DFE) generates an output sequence of DFE decision symbols; a second feed forward equalizer (FFE) generates a second equalized output symbol sequence; and correction logic, responsive to determination of an end of burst error position of a burst error sequence in the DFE output sequence, determines a candidate earliest start of burst position, and determines the corrected output symbol sequence by comparing the second equalized output symbol sequence with candidate symbol sequences that correspond to corrections of DFE decision output symbols in the burst error sequence.

Burst error detection and correction

A method and apparatus for signal equalization are provided. Multiple decision components are arranged in a sequence, beginning with a history portion and ending with a decode portion. Each decision component performs a decode decision on a symbol. Decode decisions are passed forward to other decision components where they can be used to compensate for intersymbol interference. Decode decision output by the history portion are otherwise discarded, while decode decisions output by the decode portion are output as a decoded signal. In the next decode cycle, input previously provided to the decode portion is again provided to the history portion, in a sliding, overlapping block manner.
