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
