Two-step soft output viterbi algorithm decoder using modified trace back
A two-step Viterbi algorithm decoder for tracing the survivor path and the concurrent path and updating a soft decision value, including a soft output Viterbi algorithm state metric unit (SOVA-SMU), which is constructed of registers and multiplexers, instead of a memory for storing survivor information for all states.
