PCA

说明：  构建PID控制器，设计P和I两个参数，并画出其参数范围(Build a PID controller, the design of the two parameters P and I and draw the scope of its parameters)

bpsk的算法实现,运行快，计算量少，误差小。 (very fast )

说明：  贪吃蛇MATLAB m文件 snake.m

EM modeling with matlab

验证了Matlab中用于计算时延的Align_Signals模块(test the block of Align_Signals)

关于OFDMA的介绍，初学者很容易理解。且有本人阅读时做下的一些笔记，愿对大家有用。(On OFDMA in the introduction, it is easy for beginners to understand. I read and have done at some of the notes, would like for all of us.)

This MATLAB .m file takes a "true" image, and an "observed" image that is the true image that has been noised with uncorrelated Gaussian noise. The function then performs Tikhonov regularization to clean up the defects in the image, with the Tikhonov term used to preserve image edges as much as possible.

利用MATLAB进行PID的仿真实验，调节参数可以分析出PID参数对系统的阶跃响应的影响。(The influence of PID parameters on the step response of the system can be analyzed by using MATLAB for PID simulation experiment. )

产生BPSK分析信号,可以设置基本S/N比等参数,并对信号画图显示.(Analysis generated BPSK signal, you can set the basic S/N than the other parameters, and signal drawing show.)

可对.txt文本进行霍夫曼编码，并计算其压缩率(Can. Txt text Huffman code, and calculate the compression ratio)
