Abstract
The Viterbi algorithm (VA) is a recursive optimal solution to the state sequence estimation problem. The recursive nature of this algorithm puts limitations on high-speed implementations of Viterbi decoders. The authors propose a nonrecursive suboptimal decoding algorithm for the PR4 channel. The new decoder has negligible performance loss
