Yi Wang · Shuju caiji yu chuli · 2003
From the view of geometrical projection, the physical significance of Neymark decomposition is described and its internal denoising mechanism is clarified by the standpoint of energy distribution. By dealing with some typical chaos signals in varied noise background, the limitation of using Neymark to reduce noise is explained and the relationship between the effectiveness of denoising by Neymark and energy distribution of target signal and background noise in embedded phase space is pointed out. Finally, based on the simulational result, the application scope of such kind of space projection method is summarized and a foundation of choosing appropriate method for processing chaos signal is provided.
