Abstract
Being an important linear block,the RS code,which has very strong capability of correcting random and burst errors,is widely used in various modern communication systems.This paper presents a RS decoder using Modified Euclidean Algorithm(MEA),and a new finitefield multiplier,which reduces the chip complexity of RS encoder and decoder,and discusses the design procedure of each blocks of (255,249) encoder and decoder in details.
A significance statement is not available in the OpenAlex record.

Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
