A Study on Error Evaluation Algorithm for The Implementation of Reed-Solomon Codes

This paper deals with the channel coding, which is adopted as an essential element for stable data transmission and storage, ranging from digital information transmission including high-speed Internet and digital broadcasting to massive data storage. Reed-Solomon coding is a representative block coding. It is used together with the interleaver because of its robustness against cohesive errors, and is adopted as a major coding scheme against the noises and channel distortions introduced into transmission channel. RS (204,188) encoding is adopted in the MPEG2 transport stream to obtain the coding gain of about 2dB. This reduces the requirement for the transmission power per bit to achieve the reference transmission error rate. In addition to the improvement of transmission data reliability, it also has the effect of enabling various transmission services due to the high transmission reliability. Since the decoder is located mostly at the end terminal equipment, it is important to design it to have advantages in implementation cost. For this purpose, we propose a simple implementation scheme for the derivative of polynomial on finite field and gave its verification through the simulation of RS(204,188) encoding and decoding.
