Abstract :
An interleaving is a concept which is used in conjunction with error correcting codes to counteract the effect of burst errors. Convolutional codes are frequently used to correct errors in noisy channels. The Viterbi algorithm is the most extensively employed decoding algorithm for convolutional codes. In this paper we present our studies of impact of interleaver on performance of Convolutional Encoder and Decoder (CODEC) for burst errors as well as for distributed errors. Also the performance of the Viterbi algorithm for different generator polynomials is presented. The hard decision with ½ rate coding technique is considered in this paper.
