[Matlab]PCM-Source-code

现代通信系统与matlab（程序）proakis版(Modern communication systems and matlab (process) proakis version)

说明：  PWM调制，将一正弦信号转化为PWM序列输出，用于驱动D类功放(PWM modulation, a sinusoidal signal into a sequence of PWM output, Class D amplifier to drive)

一种系统辨识方法，基于辅助模型对输出误差系统进行未知参数辨识(AM_FG.m for the output error models)

GSO算法及其改进，其中HGSO是通过与和声搜索算法结合而成，主要用于结构的截面优化、几何优化、动力优化、拓扑优化等，具有收敛速度快，收敛结果好的优点，且其改进算法能摆脱局部最优的缺陷。(GSO algorithm and its improvements, HGSO is through a combination of harmony search algorithm, mainly used to optimize the structure of the cross section, geometry optimization, dynamic optimization, topology optimization, a fast convergence, convergence results is good, and its improved algorithm defects can get rid of local optimum.)

本程序用来生成线性群时延滤波器，用于产生基带线性群时延，4倍上采样， 带内最大群时延失真为k个码元(This programme is designed to generate a linear group delay filter)

用MATLAB仿真雷达的函数，包括解调、混合、调制、PAM、PSK、及压缩编码等(Radar simulation using MATLAB function, including demodulation, mixing, modulation, PAM, PSK, and compression coding)

改进的预测控制，结合了一般的算法，但增加了预测控制对象是否稳定的判断(predictive control)

greypred.rar用于GDP预测，较为精准，误差小，程序简单，容易操作，实用。是很好的预测程序。(liner fit)

傅立叶相位加密，用于图像加密，效果好，需要密钥图像，也在压缩包里。适用于灰度图象。(Fourier phase encryption for image encryption, which is good, need to key images, but also compressed bundle. Apply to the gray-scale image.)
