本课题主要研究当信道中的加性噪声为高斯白噪声时，对接收端数字信号的判决带来的影响。 通过实验的手段分析信道无噪声的情况时，对接收端译码译码带来的影响；通过实验的手段分析信道有噪声的情况时，对接收端译码译码带来的影响； 代码可直接运行，包括基带下的误码率仿真，频带下的仿真，以及相互间的对比。界面很好(Signal in channel transfer process, not only by the channel itself, it brought, also influenced by the additive noise, Gaussian white noise is a communication channel additive noise. The main subject of study when the additive channel noise is white Gaussian noise, the impact of digital signal on the receiving end of judgment. By means of analysis of the experimental channel without noise, the impact on the receiving end decoding decoding noisy channel decoder decoding on the receiving end, the impact by means of analysis of the experiment )

是学习PCA特征提取的很好的学习资料，本程序的性能已经超过其他算法，线性调频脉冲压缩的Matlab程序。( Is a good learning materials to learn PCA feature extraction, This program has exceeded the performance of other algorithms, LFM pulse compression of the Matlab program.)

基于Wolf方法计算Lyapunov指数，直接运行文件Wolf_3DLyapunov.m(Wolf calculated based on the Lyapunov exponent, Run the file directly Wolf_3DLyapunov.m)

对齿轮箱故障进行提升小波去噪分解重构，准确判断初故障类型(Gearbox fault on lifting wavelet de-noising decomposition and reconstruction and accurately determine the beginning of the fault type)
