Hilbert-Huang transform (HHT) is a novel signal processing method which can efficiently handle non-stationary and nonlinear signals. Two key parts are included: Empirical Mode Decomposition (EMD) and Hilbert transform. EMD decomposes signals into a complete series of Intrinsic Mode Functions (IMFs), which capture the intrinsic frequency components of the original signals. Hilbert transform is adopted...
