Abstract

Due to the envelope fitting problem exists in the process of empirical mode decomposition, this paper proposed an improved algorithm which could eliminate the undershoot phenomenon exactly. By introducing pseudo-extreme points, this algorithm increased the number of extreme points and formed new extreme value sequence. Then it got new envelope by using the new extreme value sequence interpolation. The envelope fitted by this method was closer to the original signal and had better smoothness. Finally, a contrast result between cubic spline interpolation and this algorithm show that the number of undershoots decreases by about 77.5%, which proves that this algorithm can effectively reduce the number of undershoot points. In addition, fitting the envelope can tightly wrap the original signal and have a better envelope.
