Optimal detection soft-output viterbi algorithm method based on tracing of fusion points, involves finding unique nodes where surviving paths converge, and converging points are fusion points

摘要

The method involves finding unique nodes where the surviving paths converge. The converging points are fusion points, and this fusion points are the part of the maximum likelihood path through the trellis diagram. These fusion points are used so that another unit updates the reliability of the bits. An INDEPENEDNET CLAIM is also included for device architecture for optimal detection soft-output viterbi algorithm based on the tracing of fusion points.
