ABSTRACT:
An analog Viterbi decoder realizes a part of the signal processing operations necessary to produce a decoded signal by, for example, calculation of branch metrics in branch metric calculation circuit, and addition, comparison, and selection an ACS circuit, using analog signal processes, to remarkably decrease the number of elements, and to realize a high speed Viterbi decoder with a relatively small size.
