Description: The main content of HHT includes two parts. The first part is Empirical Mode Decomposition (EMD), which is proposed by Huang. The second part is Hilbert spectrum analysis (Hilbert Spectrum Analysis, referred to as HSA). In simple terms, the basic process of HHT for the treatment of non stationary signal is: first using the EMD method to a given signal is decomposed into several intrinsic mode functions (with Intrinsic Mode Function or IMF, also called intrinsic mode function), the IMF is satisfying certain conditions component; then, Hilbert transform is performed on each one IMF, get the corresponding to each Hilbert spectrum, IMF said in a joint time-frequency domain; finally, summarize all the IMF Hilbert spectrum will get the original signal Hilbert spectrum.
