EMD Endpoint Suppression Based on Waveform Means Continuation

Aiming at the endpoint effect existing in the empirical mode decomposition at the current stage and the limitations of the existing methods to solve this problem, this paper proposes a waveform mean continuation method. The method mainly focuses on the calculation method of waveform difference degree and the waveform mean value extension method, which can suppress the signal edge distortion, and effectively solve the endpoint effect problem by performing signal mean value continuation. Extensive experimental results suggest that the proposed approach can achieve better suppression effect on the endpoint effect of signals with periodic characteristics.
