VMD

说明：  matlab的命令大全，希望对大家有帮助呵呵，主要是一些命令咯 (Matlab orders, hope to help you, is mainly some orders)

OFDM and demodulation

用于处理简单实验数据的曲线预测，可通过修改函数完成相关的插值或拟合工作(For curve prediction process simple experimental data, to be completed by the relevant interpolation or fitting work by modifying the function)

阀值去噪 用db1小波对原始信号进行3层分解并提取系数(Db1 wavelet threshold de-noising with the original signal decomposition and extraction coefficient of 3 layers)

说明：  利用MATLAB进行的画图软件，很齐全，有助于初学者学习画图(Drawing conducted using MATLAB software, it is complete, will help beginners to learn drawing)

Watermarking text to image by using watermarking

有关MATLAB软件使用的介绍.主要介绍matlab优化工具箱中的常用命令及解决的问题.(the MATLAB software introduction. Introduced Matlab optimization toolbox of common fate Order and to resolve problems.)

说明：  该算例是利用蒙特卡罗算法来实现对pi的估值，压缩包中有运行结果图及程序说明，程序是用matlab代码实现(The study is the use of Monte Carlo algorithm to achieve the valuation of pi, compressed package in the results map and description of the procedures, the program code with matlab)

自己写的一个关于非零频的LFM信号的产生，及下混频到零频的代码，有详细的注释(A non-zero frequency LFM signal generation, and under the mixer to the zero-frequency code, with detailed comments)

说明：  一本书上的小波变换的数字水印程序，非常简单(A book on the wavelet transform of the digital watermarking process, a very simple)
