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.
