New Method to Solve the End Effect of Empirical Mode Decomposition

The end sifting method has been proposed to solve the end effect problem of empirical mode decomposition (EMD). During the intrinsic mode function (IMF) sifting process by EMD method, a procedure including end effect judgment and end sifting, which is different from the traditional idea dealing with the problem by dictating or predicting an end point, is added. This method has greatly improved the precision of IMF.
