Abstract

Both Viterbi decoding with labels (i.e., the Yamamoto-Itoh scheme) and thesoft-output Viterbi algorithm (SOVA) evaluate the metric difference between the maximum-likelihood (ML) path and the discarded path at each level in the trellis. Noting this fact, we shaw that the former scheme also providesinformation about the reliability values for decoded information bits.
