Deal with boundary effect of EMD method based on Improved Characteristic Wave Extending

摘要：

Empirical Mode Decomposition (EMD) is a new way to process the non-stationary and nonlinear data. But the edge effect or boundary effect appears when spline interpolation is used to get two envelopes of the data. A novel method based on improved characteristic wave algorithm is proposed to prolong the data series and get extra-extremes to deal with the edge effect. Two simulated signals are decomposed by three methods for comparison: ‘Extending Method with Characteristic Wave’, ‘Extending Method with Mirror Imaging’, and ‘Extending Method with Improved Characteristic Wave’. Experimental results show that the proposed method restrains the edge effects effectively.
