SIMU1

使用matlab实现OFDM系统功能并仿真验证其功能 (Use matlab to realize the OFDM system simulation)

一个舰船噪声信号仿真建模的程序，已经测试通过，并且可以实际应用，修改参数即可仿真各类特殊的信号(A ship noise signal simulation and modeling procedures have been tested, and practical application, modify the parameters to simulation of various types of special signal)

直方图均衡化及亮度调整，关于图像处理方面最基本的几个程序(Histogram equalization and brightness adjustment, image processing on a few basic procedures)

给定极化状态的相位描述子和幅度描述子，绘制该极化状态的poincare功率球。源代码是matlab子函数，输入参数两个：极化状态的幅度描述子和相位描述子。还有一张示例图(Given the polarization state of the phase and amplitude descriptors descriptors, to draw the polarization state poincare power ball. Functions matlab source code, two input parameters: the polarization state and phase amplitude descriptor descriptor.)

对大量数据进行pca分析，得到表达信息的重要成分，压缩数据(PCA)

这是本人精心做的,真的做的不好,我也是费了好大的心力来研究这个工作,也是我第一次来做关于matlab的源程序(this is carefully done, I really do not, and I also spent a lot of effort to study the work, is the first time I have to do on the source Matlab)

该程序代码用于求解超越方程，绘制频散曲线，自行可以更改基本参数或方程形式加以利用(Solve the transcendental equation, draw the dispersion curve)

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.)

说明：  matlab例子自适应滤波最陡下降法特征值扩散度仿真，变步长仿真(Matlab example of adaptive filtering steepest descent method for eigenvalue proliferation simulation, variable step simulation)
