Empirical Mode Decomposition (EMD) algorithm is defined by algorithmic process, rather than defined by the theoretical formula defined, so accurate theoretical analysis of it is very difficult, we can only rely on a large number of digital simulation experiments continue to its performance Conduct in-depth research. The purpose of the EMD algorithm is to decompose a signal with poor performance into a group of IMF Intrinsic Mode Functions, and the IMF must satisfy the following two properties: (1) The number of extreme points (maximum or minimum) and the number of zero-crossing points of the signal are equal or at most differ by one; (2) The average of the upper envelope composed of local maxima and the lower envelope composed of local minima is zero.
