直接序列扩频通信系统仿真程序，包括伪随机序列产生、扩频、加噪、接收等。(Direct sequence spread spectrum communication system simulation program, including the pseudo-random sequence generator, spread spectrum, plus noise, the receiver and so on.)

用matlab产生自相关系数固定的序列,然后再观察其功率谱密度.(using Matlab correlation coefficient derived from the fixed sequence, and then observed its power spectral density.)

论文 matlab 基于小波变换的信号去噪方法研究(Paper matlab signal denoising based on wavelet transform method)

本设计采用了一种基于三参数组合的方法对语音信号进行了清/浊音判决。在传统两参数（短时能量和过零率）算法基础上增加了自相关函数作为判决参数，减少了清/浊音信号误判率。(This design uses a combination of methods based on three parameters of the voice signals of the Qing/voiced sentence. In the traditional two parameters (short-term energy and zero crossing rate) algorithm based on the increase since the correlation function as a decision parameter, reducing the clearance/voiced signal false positives.)
