采用时域平滑FAM法画出的信号循环谱图，其中包括FAM子函数和画图的主函数(FAM time-domain method used to draw a smooth spectrum of the signal cycle, including FAM Functions and main function of drawing)

此源代码应用于OFDM仿真，一个OFDM符号128个有效符号，插入128个虚拟子载波(OFDM emulation)

matlab的经典学习资料，是《matlab程序教程》的源代码，有助于你matlab编程能力的提高(Matlab classical learning, "Matlab procedural manuals," the source code, Matlab programming help you in improving their ability to)

说明：  功率分配时非常有用的注水算法 数字通信课程有讲到(Very useful when the power allocation algorithm for digital communication courses injection mentioned)

一个端点检测程序，用matlab编写。endpoint detection(an endpoint detection procedures, using Matlab prepared. Endpoint detection)

一个很好地主元分析（PCA）程序~~~~~~(A good Principal component analysis program！)

1. 构造含噪音的振动信号 faultysignal_with_noise， 2. 利用小波变换 Wavelet transform去噪，小波包 Wavelet packet transform 变换去噪， 3. 把两种去噪后的信号，分别用STFT ,FFT ,小波变换三种方法进行错误诊断(1. the vibration signal faultysignal_with_noise, which contains noise, is constructed. 2. using wavelet transform Wavelet transform denoising, wavelet packet Wavelet packet transform transform de-noising, 3. the two kinds of denoising signals are diagnosed by three methods, STFT, FFT and wavelet transform respectively.)
