该文件里有一个关于DSP学习的MATLAB程序源代码，很实用(The file has a DSP to learn MATLAB on the program source code, very practical)

this is some code for modulation and demodulation

本文所做的主要工作为：研究了JPEG2000标准的原理和基本框架，对JPEG 2000标准的核心—小波变换压缩技术进行了分析研究，概要的介绍了小波理论。对EZW算法进行了详细分析和描述，包括零树的含义、结构及其扫描方法。并应用Matlab图像处理工具箱和小波分析工具箱对图像小波变换处理，并通过接口工具Mex实现在Matlab环境下对C程序EZW编码的调用，实现了应用零树小波编码算法对图像的压缩处理，简单地实现了对JPEG 2000的仿真。(The main work that this text do is:Studied the principle and basic frames of the JPEG2000 standard, to the center of JPEG 2000- Wavelet transform compress which had been analyzed and researched .Carried on the detailed analysis and descriptions to the calculate way of EZW, include zero-tree coding, structures and it’s scans method. In Turbo C environment using C language to simulate wavelet zero-tree coding algorithm, using Matlab image processing toolbox and wavelet analysis toolbox, and using interface tool Mex to implement transferring the C program in Matlab, and implement the image compress by wavelet zero-tree transform coding methodology,and supplely implement JPEG2000.)

生成一个随机序列，然后对其进行HDB3编码，最后对其解码，显示出来(Generating a random sequence, then subjected HDB3 encoding, and finally decodes, displayed)

进行PCA分解，由迭代算法，算出得分向量和负荷向量(something about PCA)

说明：  使用VC++调用Matlab程序，利用自带的Matlab引擎实现数据交换。(Using VC++ calling Matlab program, using the Matlab engine comes with data exchange.)

用于信号处理中的峰值检测，里面有demo，可以直接运行(peak finder)

一个非常红的画图程序，非常有意思，再此上传下(A very red paint program, very interesting, upload it again next)

Unit Commitment Methods to Accommodate High Levels of Wind Generation

计算阶次分析的案例，需要转速信号进行角度域重采样。(In the case of order analysis, the angle domain resampling of speed signal is needed.)
