1. A receiver for providing a corrected output symbol sequence, the receiver comprising:
a. a decision feedback equalizer (DFE) for generating an output sequence of DFE decision symbols based at least in part upon an input symbol sequence;
b. a second feed forward equalizer (FFE) for generating a second equalized output symbol sequence based at least in part upon the input symbol sequence; and
c. correction logic, responsive to determination of an end of burst error (EoB) position of a burst error sequence in the DFE output sequence, that is operable to:
i. determine a candidate earliest start of burst (SoB) position; and
ii. determine the corrected output symbol sequence based at least in part upon a sequence comparison of the second equalized output symbol sequence with candidate symbol sequences that correspond to corrections of DFE decision output symbols in the burst error sequence,
iii. wherein the sequence comparison includes a comparison of symbols residing between the candidate earliest SoB position and one position after the EoB position (inclusive).
