| 摘 要： | RS码是目前最有效、应用最为广泛的差错控制编码方式之一.CMMB系统中采用RS码作为信道编码的外码,既可以纠正数据信号传输中的随机错误,又可以纠正由于噪声等造成的突发错误.本文在分析CMMB系统中RS码编码原理的基础上,设计了一种基于FPGA的RS编码器,并重点分析了其中能够实现高速运算,且结构简单的的乘法器.

| Abstract: | At present,RS code is one of the most effective and most widely used forms of error control coding.CMMB system uses RS code as outer code of channel coding,which corrects not only the random errors in data transmission,but also burst errors owing to the noise.In this paper,based on analyzing the coding theory of RS code in CMMB system,RS encoder is designed by taking advantage of the FPGA,the multiplier in RS encoder with simple structure which can achieve high-speed operation is another focus of the analys... |
