Description: Empirical Mode Decomposition method (Empirical Mode Decomposition, the EMD for short) is a chinese-american n. e. Huang et al., in 1998, is suitable for analyzing nonlinear and non-stationary signal sequence, has the very high signal-to-noise ratio.Empirical Mode decomposition is a key to this method, it can make the complex signal is decomposed into a finite number of Intrinsic Mode Function (the Intrinsic Mode Function, the IMF), the decomposition of each IMF component contains the original signals of the local characteristics of different time scales.
