长距离无线数字通信中的信道编码设计

摘要

This paper introduces a method of designing the channel coding on long-distance wireless digital communication, in order to enhance the quality of communication,(255,233)RS code and(2,1,7)convolu-tion code are cascaded by (8,255) inter-leaver. The MATLAB simulation result shows that cascaded code will be widely used in wireless digital communication region because of its low error rate.%介绍了一种长距离无线数字通信中的信道编码设计方案。为改善通信质量，采用了（255，233）RS编码+（8，255）交织+（2，1，7）卷积编码这一信道编码方式。MATLAB仿真结果表明，该级联码能有效降低数字通信系统的误码率，在无线数字通信领域中有着很好的应用前景。
