《高等光学仿真》第一版的第三章源程序，主要是关于单模光纤和多模光纤的特征方程(" Advanced optical simulation," the third chapter of the first edition of the source, mainly on single-mode fiber and multimode fiber characteristic equation)

一个简单的四则运算计算器，它能实现两个数据的加减乘除运算，数据需手动输入。因为界面相对简单，方便初学者使用学习(A simple four-function calculator, it can achieve two data arithmetic operations, data to be entered manually. Because the interface is relatively simple and easy to learn for beginners)

一个关于指纹识别的MATLAB编程，对大家会有帮助的(A fingerprint identification on MATLAB programming, it would be helpful to everyone)

调制识别是非协作通信中的关键技术之一，在电子对抗、软件无线电等领域 应用十分广泛。该过程介于信号检测与解调之间，由于对传输信号没有过多的先 验信息以及在接收端有很多未知的参数，例如：信号功率，载波频率和相位偏移， 时间信息等，导致对调制方式的盲识别是一项很困难的任务。此外，实际中存在 多径衰落、频率选择性和时变信道等问题，使得这项任务变得更具有挑战性。 (The modulation recognition is one of the key technologies of the non-cooperative communication, such as electronic countermeasures and software defination radio, therefore it is such a significant discipline and orientation in the research of communication field. Obviously, without enough knowledge in transmitter and verified parameters about receivers, for example signal power, carrier frequency and phase offsets and so force, it is hard to get the modulation of blind identification. What is more, for the sake of the multipath fading, frequency-selective and time-varying channels in the real scenarios the task is even harder. )
