This m-file is written in MATLAB. It instroduces a simple method to create a PID controller

本文是基于3路径的rake接收机，在高斯噪声下的三种合并方式的误码率比较。(This article is based on the path of the rake receiver 3, in the three combined Gaussian Noise BER comparison approach.)

sar成像最后如果要查看结果，就是这个程序实现的功能，画出峰值旁瓣比！(sar imaging Finally if you want to see the results, is the function of this program, draw peak sidelobe ratio!)

对于初学者来说，有助于理解滤波器的原理还附有简单的matlab编程(For beginners to understand the principles and simple filter matlab programming)

在仿真中通常利用3GPP中的scm信道来模拟MIMO信道，各个scm信道是独立产生，相互之间独立，即相关系数为零。(Often used in the simulation of the 3 GPP SCM channel to simulate the MIMO channel, the SCM channel is independent, independent with each other, the correlation coefficient is zero.)

参考外国文献，通过MATLAB程序编写了以两个简单的vIBtiJ映射构造一个双混沌互扰 uNACsXn系统,提出了基于双混沌互扰系统的无线加密算法，具有防窃听的能力，调试无错误。(References to foreign literature, through MATLAB programming the vIBtiJ with two simple mapping to construct a mutual interference uNACsXn dual chaotic systems is proposed based on the wireless encryption algorithm dual chaotic mutual interference system has the ability of anti-wiretapping, debugging errors. )

实验三、四阶Runge-Kutta法求解初值问题，是我的实验报告。(The third experiment, fourth-order Runge-Kutta method to solve initial value problems, is my lab report.)

基于傅里叶变换的混沌图像置乱加密方法及其代码实现(Fourier transform based on chaotic image encryption and scrambling code implementation)

用来获取天线 array factor 参数(get the array factor from the Antenna)
