This file includes the source code of the Uncoded OFDM 16QAM with AWGN channel..

本程序为通信系统中的MSK调制程序，对于研究通信调制解调的人来说十分有用！(This procedure for the communications system MSK modulation process, the study of communication modem very useful for people!)

说明：  双馈风力发电机是一个复杂的多变量非线性系统，利用Matlab软件中的S函数编程建立双馈风力发电机模型，并通过仿真验证了其正确性。(Wind Generator is a complex multi-variable nonlinear system, Matlab, S-function software programming model for the establishment of double-fed wind generator, and simulation results show its validity.)

基于1962年Gallager提出的规则LDPC码构造方法实现的生成相应LDPC校验矩阵的相应matlab程序。只需要输入相应的码长，列重，行重即可得到具体的矩阵。(1962 Gallager based on the rules LDPC new method of generating the corresponding LDPC calibration matrix corresponding Matlab procedures. Only need to import the corresponding code length, the series, can be re-specific matrix.)

预测函数控制的英文书籍很有用，包含很多内容(English books useful predictive function control contains a lot of content)

应用于三自由度车辆模型的扩展卡尔曼滤波程序(Extended Kalman Filter controllrt for Three degree of freedom vehicle model)

该书为冈萨雷斯的数字图像处理及MATLAB实现，该书介绍了数字图像处理技术和MATLAB图像处理技巧(Gonzalez book digital image processing and MATLAB implementation, the book introduces digital image processing technology and MATLAB image processing techniques)

本文主要讨论获得图片后如何提取其边界信息，首先利用图像灰度均匀化解决了对比度不清晰的问题，然后利用高斯滤波法对图片进行滤波去噪，进而利用Canny算法实现边缘检测提取边界，该方法与Matlab自带的求边界方法有明显的提高，为利用Matlab程序求图像分形维数提供了更精确的前提。(This article focuses on how to get the image to extract the boundary information, the first to use to the gray uniform solve the contrast is not clear, and then use the Gaussian filter image filtering noise, and then use the Canny edge detection algorithm to extract the boundary of the and Matlab comes boundary method has increased significantly, and provide a more accurate premise for the use of Matlab program for image fractal dimension.)

The quantum particle swarm optimization (QPSO) applies the quantum computing theory to particle swarm optimization, and thus has the advantages of both quantum computing theory and particle swarm optimization, so it has a faster convergence rate and a more accurate convergence value.
