Improved Intrinsic Time-scale Decomposition Method and Its Simulation

摘要：

　　Aiming at relieving the mode mixing of the intrinsic time-scale decomposition (ITD)method used to process the intermittent signals,the improved intrinsic time-scale decomposition(IITD) method is proposed in the paper.The IITD method employs white noise which has the uniform power distribution in different frequencies as a reference to resolve the problem.Furthermore,a simulation signal was utilized to examine the performance of the IITD method as well as that of the original ITD method.As a result,the comparison between the results from the two methods indicates that the IITD method reflects an obvious improvement on the original ITD method for processing the intermittent signals.
