RS码在汉信码中的纠错性能分析及仿真

Analysis and Simulation on Error Correcting Performance of RS Code in Chinese Sensible Code

对汉信码所采用的RS纠错码的纠错方法进行研究,探讨了如何采用MATLAB工具实现汉信码中RS码的编码和译码,并对其纠正随机错误和突发错误的性能进行了仿真,得到不同的误码率-信噪比曲线,这些曲线反映了RS码纠错能力与码长及校验位长度的关系。研究结果为汉信码的工程实现和评估汉信码传输可靠性提供了理论依据。

The error correcting method using Reed-Solomon（RS）code applied to Chinese sensible code is studied.The way of how to achieve the encoding and decoding of RS code used in Chinese sensible code by MATLAB is introduced.The performance simulation of correcting random errors and burst errors are implemented by MATLAB.The different curves of bit error rate and signal noise are obtained through the simulation,and these curves reflect the relationship between error correcting performance and the code length.The results provide theoretical basis for the engineering realization and the transmission reliability evaluation of Chinese sensible code.
