说明：  这个程序是描述了跳频系统在部分边带干扰下的BFSK系统的仿真，主要是误码率计算函数(This procedure is described in some side-band frequency-hopping system under the disturbance of the BFSK system simulation, bit error rate is mainly a function)

利用matlab语言实现的DES算法，其特点是加入了UDP发送与接收模块，可以实现加密数据后的网络发送与接受后的解密(The use of DES algorithm matlab language, which is characterized by adding UDP send and receive modules can realize the network send and receive encrypted data after decryption post)

这是matlab版的视频水印，仅供初学者参考。(This is videowatermark code.)

数据的极差标准化程序和数据,应用于matlab( data normalization)

Matlab编程（Stephen.J.Chapman编.刑树军.郑碧波译.），适用于初学者快速入门。(Matlab programming, suitable for beginners to get started quickly.)

基于MATLAB的平面度评定方法，介绍了计算方法(Based on MATLAB flatness evaluation method, calculation method introduced)

蚁群算法是受真实的蚂蚁群体行为启发而得出的一类仿生算法。采用蚁群算法，设计好蚁群系统，利用MATLAB进行仿真，解决函数优化问题。(Ant colony algorithm is inspired by real ants swarm behavior and it is concluded that the category of bionic algorithm. Using ant colony algorithm, design good ant colony system, use of MATLAB simulation, to solve the function optimization problem.)

简单的matlab画标定板程序，用以生成像素级的标定模板，直接打印，避免了其他方法画出标定板产生虚边的问题。(Simple matlab drawing board calibration procedure to generate a pixel-level calibration template, print directly, avoiding the other methods to draw the calibration panels to generate virtual edge issue.)

很多MATLAB的无线系统仿真实例。强烈推荐！(A lot of MATLAB simulation of wireless systems. Strongly recommend!)
