programation matlab de tp de traitement

说明：  一个用MATLAB实现的CA滤波模型，适合初学者，文件不长稍微有点基础的都能看懂(A the CA filter model using MATLAB, for beginners, file does a little bit of foundation can understand)

非线性信道matlab仿真程序，可以实现色散和非线性效应(nonlinear fiber)

包含轴承故障数据，来源于MFPT（Machinery Failure Prevent Technology）论坛，分四组训练数据和测试数据； 数据可直接做频谱分析，效果很好(contain bearing faults data sets, 4 train datas and 4 test datas, can be used for FFT/envespectrum analysis, and you will get perfect effects.)

Formation of Alien in matlab..............

此代码用于故障诊断特征提取，所提取特征包括传统时、频域特征和时频特征三部分，数据为轴承数据(This code is used when troubleshooting feature extraction, the extracted features, including traditional, frequency domain and time-frequency characteristics of three parts, the data is bearing data)

Zigler Nichols method program in Matlab

说明：  采用小波对信号分解和去噪。分解层数和使用的小波可以自己定义然后阈值去噪(Wavelet is used to decompose and denoise signals. The decomposition level and the use of wavelet can be defined by itself and then threshold denoising)

基于线性滤波法的风速时程MATLAB程序(MATLAB program based on linear filtering method of wind speed time)

对AM信号和QPSK信号的功率谱进行了比较，包含这两种信号的产生和功率谱的产生方法，具极强的参考价值(AM signal and the power spectrum of the QPSK signal, including both signal generation and the generation method of the power spectrum, with strong reference value)
