ABSTRACT:
A serial Viterbi decoder in which a single set of circuits is sequentially used for all the encoder states to calculate the maximum probability path, as measured against received signals, of unencoded signal sequences to reach each encoder state. The path to any encoder state having the maximum probability is traced back to output the oldest encoded signals.
