Reed-solomon system and problem

Reed-Solomon (RS) codes are widely employed for error correction due to its distinct capability of correcting both random and burst errors.Complexity of RS encoder and decoder increases with the error correcting capability of the codes.The code is very much suited from VLSI design viewpoint and requires more hardware and power for decoding is high.This leads to the design of CA based Codec. 

One weakness of the Reed-solomon system is that single byte error in mth information byte and double byte errors (one in mth information byte and another in the last information byte) correspond to same equation for error location identification.This System can correct errors provided errors are confined to information or check byte only. The system cannot correct if the errors are distributed both in information and check bytes.
