Abstract :
Although Viterbi decoding is widely used in practical systems, only a few studies have been made for the exact error performance. We already proposed analytical technique for a 2-state soft decision Viterbi decoding. In this paper, this technique is extended to bit error probability for 4-state soft decision Viterbi decoding. This employs an iterative calculation of probability density function (PDF) of the path metrics
