摘　　要：几乎所有的现代通信系统都把纠错码作为一个基本组成部分。RS码由于具有较强的纠正突发错误的能力,已经被NASA、ESA、CCSDS等空间组织接受,用于空间信道纠错。该文针对CCSDS标准中两种RS码进行了研究和实现,提出了一种码率兼容的RS码译码器,有效降低了硬件存储资源。Almost all modern communication systems take error correction code as a basic component.RS code has been accepted by NASA,ESA,CCSDS and other space organizations for space channel error correction because of its strong ability to correct burst errors.In this paper,two RS codes in CCSDS standard are studied and implemented,and a rate compatible RS code decoder is proposed,which effectively reduces the hardware storage resources.

关 键 词：RS码 码率兼容 译码器
