基于折线包络的经验模态分解方法

Folding-line-envelope-based Empirical Mode Decomposition Method

提出了一种基于折线包络的经验模态分解方法。以一个具有明确解析表达式的信号验证了该方法所得结果的意义,并讨论了该方法分解El Centro波所得固有模态分量(IMF)的波形与频谱特征。

A folding-line-envelope-based empirical mode decomposition method is proposed in this paper. We discussed the significance of the results of this method is validated by a signal with definite analytical expression, and the characteristics of the waveforms and spectra of the intrinsic mode functions （IMF） resulted by decomposing the E1 Centro waveform by using this method.
