symbol rate estimation of linearity modulation signals

对利用录音设备对手机、电话等按键式密码输入终端进录音盗取银行卡密码的不法行为进行技术分析，利用MATLAB软件编程对按键式密码输入终端的按键音进行音频分析，基于短时能量和过零率对所采集的音频文件进行端点检测，提取出单个拨号音，然后对处理后的音频进行频谱分析、对比，从而识别按键式密码输入终端的按键音。(On the use of recording equipment on the phone, telephone touchtone input terminal password into the recording steal bank card passwords wrongful conduct technical analysis using MATLAB software programming for touch-tone touchtone password input terminal for audio analysis, based on short-term energy and zero-crossing rate of the acquired endpoint detection audio files, extract single dial tone, and then processed audio spectrum analysis, comparison, to identify key tone touchtone password input terminal.)

PSO-LSSVM算法的matlab实现，利用PSO算法对LSSVM模型的初始参数求解，以期望得到最好的模型。(PSO-LSSVM algorithm is implemented in matlab, and PSO algorithm is used to solve the initial parameters of LSSVM model in order to get the best model.)

本程序是本人根据人脸识别PCA改进的，用于掌纹识别，是学习PCA特征提取的很好的学习资料。(I based this program is to improve the face recognition PCA for palmprint identification, PCA feature extraction is to learn a good learning materials.)

对时间序列或者信号进行fft谱分析，可以打开任意数据文件后分析，很方便使用。(FFT transfer of matlab code,it is useful for signal analysis.)

基于MATLAB的kNN分类器，两组简单的代码，希望能有一定的用处(KNN classifier based on 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)
