Description: 今天看了些EMD信号分解方面的东西，matlab官网上有个Hilbert-Huang Transform的代码，代码效率极高啊，人家3句语句就解决了一个大问题，很牛啊！还有一个GRilling的EMD工具箱，好多文件，功能应该相当强大。
这里研究了研究matlab官网的代码，加了些注释、功能演示，效果如下
原始信号由3个正弦信号加噪声组成，如下-Today looked at some of the EMD signal decomposition of things, matlab official website has a Transform Hilbert-Huang code, the code efficiency is very high, ah, the people of the 3 sentence to solve a big problem, it is cattle ah! There is a EMD GRilling toolbox, a lot of documents, the function should be quite strong.
Here to study the Matlab s official website code, add some notes, function demonstration, the results are as follows
The original signal is composed of 3 sinusoidal signals with noise, as follows Platform: |

Description: 基于经验模态分解法（EMD）的Hilbert-Huang变换（HHT）的MATLAB程序。
可将非平稳信号转换为平稳信号，通过将IMF分量累加重构得到平稳信号 。
主程序为HHT.m，需要用到hhspectrum.m函数、instfreq.m函数（在压缩包内）和已安装的EMD工具箱中emd函数。(The empirical mode decomposition (EMD) method based on Hilbert-Huang transform (HHT) of the MATLAB program.
The non-stationary signals can be converted into stationary signals, and the stationary signals can be obtained by accumulating and reconstructing the IMF components.
The main program is HHT.m, which requires the hhspectrum.m function, the instfreq.m function (in the compressed packet) and the EMD function in the installed EMD toolbox.) Platform: |
