A New Method for Time Series Signal Decomposition

Because extending methods play a very important part in Empirical Mode Decomposition (EMD) given by Huang et al in 1998. One new efficient method for several time series signal decomposition based on EMD is presented in this paper. The method is tested to several time series decompositions. We have compared the results with those of N. E. Huang et al. and D. J. Huang et al. The comparison shows that this method is more feasible and more precise.
