这是一个研究生课程的matlab课件，方便大家学习matlab，希望能给大家带来帮助(This is a post-graduate courses matlab courseware to facilitate learning matlab, hope everyone can help)

两个噪声信号及噪声信号和含噪声周期信号的互功率谱。 采用多窗口法估计含有周期信号的功率谱。(The two noise signal and noise signal and noise periodic signal containing the cross-power spectrum. Multi-window method is estimated to contain periodic signal power spectrum.)

本程序基于“图像模式识别—VC++技术实现”写就，实现了线性和非线性手写数字识别。 程序主文件是homework.m 具体实现可以参考程序内注释。 (this is a matalb programme,in order to recognise the number writtern by yourself. it include homework.m,homework.fig,Getfeature.m,losstab.m,losstab.fig,samplelib.m,samplelib.fig,save_sample.m,save_sample.fig)

此为matlab编的聚类程序，可以快速的对位置样本进行聚类(This is a matlab series clustering procedure, you can quickly sample clustering of the position)

OFDMmatlab仿真程序，改程序是一个仿真系统，附有文档说明。(OFDMmatlab simulation program, the reform process is a simulation system, accompanied by documentation.)

模糊PID控制，不需调试，可直接输出图像(Fuzzy PID control, without debugging, can be directly output image)

数字基带信号的传输是数字通信系统的重要组成部分。在数字通信中，有些场合可不经过载波调制和解调过程，而对基带信号进行直接传输。HDB3码的作用是对数字基带信号进行编码，便于在接收端对定时分量的提取。(Digital baseband signal transmission is an important part of digital communication system. In digital communication, some occasions without carrier modulation and demodulation process, and to direct transmission baseband signal. HDB3 code is used to encode digital baseband signal, facilitate at the receiving end of timing component extraction. )

永磁同步电动机直接转矩控制论文,其中比较了滑模观测器和kalman滤波器的优缺点(SMO-KF compare used in DTC for PMSM drive)

模糊度窄带，分为为单频信号，线性调频，双曲调频信号。通过模糊度椭圆计算时间分辨率和频率分辨率。(Narrowband ambiguity, divided into single-frequency signal, chirp, HFM signal. Computing time resolution and frequency resolution through ambiguity ellipse.)
