说明：  图像的置乱加密和解密算法，需要输入加密密钥进行加密，然后只能输入相同的解密密钥才能得到原图像(Image scrambling encryption and decryption algorithms, need to enter the encryption key to encrypt, then enter the same decryption key only to get the original image)

说明：  这些MATLAB的M文件分为两部分：程序清单A中收录了产生PPM-TH和PAM-DS这两个信号源的所有函数；程序清单B中收录了加性高斯白噪声（AWGN）信道建模，正交和非正交单脉冲PPM-TH接收机结构，以及反极性PAM-DS单脉冲接收机结构仿真所需的所有函数。(The MATLAB M-file is divided into two parts: A list of procedures in the collection of produce PPM-TH and PAM-DS two signal sources all functions Listing B, contains an additive white Gaussian noise (AWGN) channel construction mode, orthogonal and non-orthogonal single-pulse PPM-TH receiver structure, as well as anti-polarity PAM-DS receiver structure simulation of single-pulse all the necessary functions.)

说明：  matlab 程序关于 bnoise的处理(matlab processing procedures on bnoise)

根据 DVB-T 欧洲标准写的一个OFDM matlab 仿真，其中包括发射器和接收器。文章中有matlab程式的详细介绍，有仿真方框图，还有每步的实验结果分析，特别适合OFDM的初学者。算是OFDM比较简单的一个入门介绍。英文也比较浅显，可读性很强(According to the European DVB-T standard to write a OFDM matlab simulation, which comprises a transmitter and a receiver. Article has a matlab program in detail, there is a block diagram of the simulation, as well as analysis of the experimental results of each step, especially for OFDM for beginners. OFDM considered a relatively simple introduction to. English is also relatively simple, readable)

无数直流电机无位置传感器速度控制。利用电机运行时产生的反电动势估算转子位置。(Sensorless speed control of numerous DC motors.The rotor position is estimated by the back electromotive force generated during the motor operation.)

MATLAB离散散点图和回归曲线图，非常好用，附有注释(MATLAB discrete scatter plot and regression curves, very easy to use, with comments)
