ABSTRACT:
A method for improving gain performance of a Viterbi decoder wherein data relating to the best path and a secondary path are stored for the Viterbi decoder. Slicer errors are determined for the best path and the secondary path for current symbols using the stored data and errors for previous symbols are corrected responsive to the determined slicer errors.
