The mirror extending approach proposed by Zhao and Huang ９in EMD method is improved in this paper.Mirror extending manner of data is kept unchanged, but the approach for determining nvelopes is changed. When the end of data is obvio usly not extremum, the envelope is determined by the first inner extremum and the image value in the mirror, ignoring the value on the end. This improvement eliminates the frequency compression near the end and decreases the erro…查看全部>>
