WebDec 7, 2024 · Huang et al. [6] developed a method for nonlinear and nonstationary signals, which is called the Hilbert–Huang transform (HHT). This method consists of two parts: the empirical mode decomposition (EMD) and the Hilbert spectral analysis (HSA). WebIII. Hilbert-Huang Transform Hilbert-Huang transform (HHT) is a new method for analyzing nonlinear and non-stationary signals which is proposed by Huang, et al. in 1998 [19]. Compared with wavelet method, HHT can eliminate the spurious harmonics that have no physical mean, and is superior to wavelet method in some applications [20].

WebNov 26, 2024 · 2.2 Hilbert–Huang Transform. HHT is a time–frequency–energy method for the analysis of nonlinear or non-stationary data sets, the process of which can be divided into two parts: EMD and the Hilbert transform (HT) . For extracting the basis for the HT, EMD has been proposed to generate finite component sets empirically from the original data.
