简单数字调制编程，方便初学者学习 简单数字调制编程，方便初学者学习(Simple digital modulation program, easy for beginners to learn simple programming of digital modulation, easy for beginners to learn)

matlab数值分析与应用matlab在微积分中的应用(calculus program )

sar成像的描述算法，具有介绍性质，入门者可以看看，效果很好。(introduction to sar iamging algorithm)

matlab通信工具箱函数，conmunications Toolbox。(matlab communications toolbox functions, communications Toolbox.)

OFDM 的全套程序， 包括调制， 解调， 误码， 眼图， 功率谱。。。(OFDM complete set of procedures, including modulation, demodulation, error, eye diagrams, power spectrum. . .)

说明：  基于随机采样的视差平面拟合 (Based on random sampling of disparity plane fitting)

对AR（4）模型的经典功率谱估计，并与真实功率谱作比较。采用了welch方法，协方差法，burg方法(For AR (4) model of the classic power spectrum estimation, and with true power spectrum for comparison. Welch method using covariance method, burg method)

关于三相SVPWM仿真的模型，我做电力电子仿真作业的一道题，花了很多时间下载和阅读文献，最后总算成功了，只是仿的结果有点慢，一直找不到为什么。 注意：此模型仿真时需要svpwm.m这个文件，并且matlab软件版本为Matlab7.1。(About three-phase SVPWM simulation model, I do the job of power electronic simulation of a question, spend a lot of time to download and read the literature, but finally succeeded, but the result of imitation of a little slow, could not find why. Note: This model simulation requires svpwm.m this file and matlab software version Matlab7.1.)

多频率点的凹口滤波，干扰对消，实现信号与噪声的分离，效果很好。(Recesses of the multi-frequency filtering, interference canceller to realize the separation of signal and noise, and the effect is good.)

根据油膜轴承特点，编制了润滑数值计算程序，实现对油膜压力的数值模拟及显示。(According to the characteristics of the oil film bearings, lubrication compiled numerical procedures to achieve the numerical simulation of film pressure and display.)
