为解决信道中的噪声影响，可采用 CMA算法。当C/A码通过噪声信道时，会产生误码。本作通过CMA算法较好的解决了这个问题。压缩文件里是一个simulink仿真，通过这个仿真不仅可以学习simulink的使用，还能较好的理解噪声对通信的影响-To resolve the effects of noise in the channel, the CMA algorithm may be used. When the C/A code through the noise channel will result in error. For this by the CMA in a better solution to this problem. The compressed file is a simulink simulation simulink use this simulation can not only learn, and also a better understanding of the impact of noise on communication
