Hilbert-Huang希尔伯特黄变换(HHT)的Matlab实现源代码免费下载-Hilbert-Huang Transform-Free Source Code

Hilbert-Huang希尔伯特黄变换(HHT)的Matlab实现源代码免费下载-Hilbert-Huang Transform-Free Source Code
代码中的plot_hht函数实现了hilbert-huang变换(hht),hht就是hilbert-huang transform(希尔伯特黄变换),美国航天航空局黄鳄教授发明的,大概的过程是:

this submission is a realization of the hilbert-huang transform (hht). the function plot_hht is a realization of the hilbert-huang transform (hht)....wikipedia.org/wiki/hilbert-huang_transform). learn more about the hht from the attached pdf.

Empirical Mode Decomposition

the empirical mode decomposition is the base of the so-called “hilbert-huang transform” that comprises also a hilbert spectral analysis and an instantaneous frequency computation.

the function plot_hht is a realization of the hilbert-huang transform (hht). the hht decomposes a signal into intrinsic mode functions (or imfs), and obtain the instantaneous frequency data. it is designed to work well for data that are nonstationary and nonlinear

this can be used to reduce the influence of end effects on analyses such as the hilbert transform, the wavelet transform, the hilbert-huang transform and emd, or hilbert vibration decomposition.
