一、前言广义RS码是一种MDS的多进制线性分组码,它的子域子码包括了Goppa码、GBCH码、Alternant码等,因此究究它的译码方法是十分有意义的。1965年Massey提出的逐步译码方法解决了BCH码在设计距离内的一般译码问题,本文则将这种译码方法推广到非循环的广义RS码。
I. INTRODUCTION Generalized RS code is a MDS multi-ary linear block code. Its subdomain subcode includes Goppa code, GBCH code and Alternant code, so it is very meaningful to study its decoding method. The gradual decoding method proposed by Massey in 1965 solves the general decoding problem of BCH code in the design distance. This paper generalizes this decoding method to the non-cyclic generalized RS code.
