摘要
介绍了补偿码的特点和性质,选取了基本的补偿码字并讨论了它们的自相关特性,以及补码键控调制的原理及实现过程。应用MATLAB对补码键控调制进行仿真,并对补码键控调制性能做了简要的理论分析,证明加了RS编解码的补码键控调制,较原始的补码键控调制在性能上有所改善,符合高速数据业务的应用需求。
Introduces the Characteristics and nature of Complementary Code Keying（CCK）.Chooses the basic complementary code,then discusses their autocorrelation feature and the principle and implementation process of CCK modulation.CCK modulation is simulated through the application of Matlab,and the performance of CCK modulation is briefly theoretically analyzed.Compared with CCK modulation,CCK with RS Codec has aim improvement in performance,meet the requirements of high-speed data services.
