Abstract

A DFE comprises a trellis decoder and a plurality of sub-filter pipelines. Each of the plurality of sub-filter pipelines is fed intermediate decoded symbols of one of the stages in a trace-back chain of a current decoding bank. The DFE output is formed by summing the plurality of sub-filter pipelines.
