摘要
针对RS码译码性能在"比特级"层面研究较少的问题,提出了利用错误图样分布来研究其译码性能的方法。在不加调制的情况下,通过设定错误图样参数,分别从RS码的监督位、信息位和全码长着手,仿真分析了不同参数下错误图样分布对其译码性能的影响。仿真结果表明,错误图样的不同分布会对RS码的译码性能产生不同的影响,错误发生在信息位时对RS码的译码性能影响较大,而在监督位出错时对RS码影响较小。
Considering that the decoding performance of RS codes in＂bits＂level is less studied,a method using error pattern distribution to analyze the decoding performance is proposed. By setting error pattern parameters,the influence of error pattern distributions on the decoding performance is simulated and analyzed without modulation with respect to the supervision bits,information bits and the whole code of RS codes separately. The results show that different error pattern distributions have different influences on the decoding performance,and the influence is greater when the error occurs in the information bits than in the supervision bits.
