摘要：Classical Viterbi algorithm (HOVA) and Soft Output Viterbi Algorithms (SOVA) are used for errorcorrection in many applications. Among FEC schemes, convolutional encoding and Viterbi decoding are the mostpopular because of their powerful coding-gain performances. In this paper the performance analysis of Convolutionalencoder and hard decision Viterbi algorithm and SOVA Bit Error Rate (BER) have been analyzed as well as comparedconsidering different constraint lengths, generator polynomials. The rate considered is ½ rate for both the algorithms.
