Soft output Viterbi algorithm
Appearance
The Soft Output Viterbi Algorithm is a variant of the classical Viterbi Algorithm.
SOVA differs from the classical Viterbi algorithm in that it uses a modified path metric which account of a priori probabilities of the input symbols, and produces a soft output indicating the reliability of the decision.
