Empirical Mode Decomposition(EMD)is a new method of non-stationary signal processing method starting to prosper in recent years,but the end effect caused by the decomposition results in serious distortion.Therefore,an improved self-adaptive waveform matching extension method is proposed to study end effect of EMD,which can determine extension points according to different characteristics of signal ends to solve the end effect problem.Experiment results show that the improved self-adaptive waveform matching extension method can avoid the distort...
