Abstract: PROBLEM TO BE SOLVED: To provide a technology for enhancing the gain performance of a Viterbi decoder. SOLUTION: The system and method of this invention stores data related to a best path and a secondary path in a Viterbi decoder, uses the stored data to decide the slicer error of a present symbol with respect to the best path and the secondary path, and corrects an error with respect to the preceding symbol in response to the decided slicer error.

Abstract: A method for improving gain performance of a Viterbi decoder wherein data relating to the best path and a secondary path are stored in two path memory units of 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.
