As a new nonlinear and non-stationary signal analysis method,local mean decomposition(LMD) has a good self-adaptability.This method can decompose complicated signals into a series of physically meaningful production function(PF) components.But performing LMD will produce end effects which make results distorted.After analyzing reasons for end effects of LMD in detail,a new method based on weighted matching similar waveform was proposed.The results from simulation signals of VEP indicate that this method can restrain the end effects effectively and get a good decomposition effect.
