利用patchwork方法，嵌入0-1水印。可设置像素修改值、选择各种经典的攻击方式和控制攻击强弱。返回提取的水印信息和峰值信噪比。利用Matlab编写。(The use of patchwork approach, embedding the watermark 0-1. Modify pixel values can be set to choose a variety of classic attacks and control the strength of the attack. Back to extract the watermark information and peak signal to noise ratio. Prepared using Matlab.)

瑞利信道下，stbc22,24,44，wuma仿真，以及通过奇异值分解的44天线的误码仿真，(Rayleigh channel, stbc22, 24,44, wuma simulation, as well as through the singular value decomposition of 44 antennas BER simulation,)

2009年9月全国大学生数学建模获奖论文所需程序代码，其中有较详细的matlab编程，应该有些用处吧(September 2009 Mathematical Contest in Modeling program code required for the award-winning paper, including more detailed matlab programming, it should be useful)

该程序是一个简单的递推最小二乘法（rls）、共轭梯度法（grad）以及黄金分割法，输入数据，能够计算出来(The program is a simple recursive least squares (RLS), the conjugate gradient method (grad) and golden section method, the input data, can be calculated)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。(This program is the most basic particle swarm optimization algorithm and Matlab, very simple.)

该程序可以让你通过设置一序列参数来获得具有一定距离的两波源实现干涉(This program lets you set up a sequence of parameters through to get some distance the two wave source to achieve interference)

运用FFT技术来综合和分析电话拨号的过程，matlab来分解了这一过程，希望能提供帮助( TOUCHTONE Use FFT to synthesize and analyze telephone dialing The dual tone multi-frequency (DTMF) standard specifies that the tone generated by a button on a telephone key pad is the sum of two sinusoids, with frequencies determined by the button s row and column. The dial pad on the upper left allows you to select buttons and generate the corresponding tones. The signal plotted on the upper right is a recording of the FAX number for the MathWorks being dialed. You can replay the entire signal, or select individual segments. The power plot is the magnitude of the FFT of the signal being played. What is the MathWorks FAX number?)
