Zusammenfassung:Devices, methods, and systems of a communications channel detector are disclosed that can compare a plurality of candidate sequences of bits and decisions to identify unlikely error events. The detector may then discard at least one candidate sequence based on an unlikely error event to produce a set of remaining paths. A branch metric calculator may be adapted to calculate metrics for a set of remaining paths.
