Abstract

Register exchange network for radix-4 SOVA (Soft-Output Viterbi Algorithm). Two trellis stages are processed simultaneously and in parallel with one another (e.g., during a single clock cycle) thereby significantly increasing data throughput. Any one or more modules within an REX (Register Exchange) module are implemented using a radix-4 architecture to increase data throughput. Any one or more of a SMU (Survivor Memory Unit), a PED (Path Equivalency Detector), and a RMU (Reliability Measure Unit) are implemented in accordance with the principles of radix-4 decoding processing.
