Woolrich 1 Author information Copyright and License information See other articles in PMC that cite the published article. Abstract WebHilbert-Huang starts with empirical mode decomposition (EMD). I know one HHT code is available on Matlab central but I personally find it not very robust and extremely sensitive to edge effects. A more robust solution may be found here : http://perso.ens-lyon.fr/patrick.flandrin/emd.html

Huang 等人[9]提出经验模态分解方法，并引入Hilbert谱的概念和Hilbert谱分析方法，称为希尔伯特-黄变换(Hilbert-Huang Transform, HHT)。希尔伯特-黄变换主要包括两个阶段，分别是经验模态分解（EMD）和 ...
