Error Control Mechanisms using CODEC
Todays communication system is susceptible to many types of errors and interferences. There are different types of error detection and correction mechanisms proposed by many authors. One of the important methods of error control is by means of encoding/decoding techniques at source/destination. In this context, we propose an evaluation process of convolutional encoder and decoder (CODEC), for the various constraint lengths and for different generator polynomials, for the given messages considering burst errors and distributed errors in the received messages. The 1/2 rate and hard decision coding is considered in this paper. Performance evaluation in terms of error correction capability of CODEC is shown through simulation using two burst error recovery techniques.
