1. A receiver comprising: a sequence estimation circuit operable to: receive a coarsely-phase-corrected signal having residual phase noise; generate a symbol candidate sequence; generate a phase candidate sequence corresponding to said residual phase noise; calculate a sequence estimation metric for said symbol candidate sequence based on said symbol candidate sequence, said phase candidate sequence, and said coarsely-phase-corrected signal, wherein said sequence estimation circuit is operable to convolve said symbol candidate sequence with a filter response prior to said calculation of said sequence estimation metric; and decide on a transmitted sequence of symbols based on said sequence estimation metric.
