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