Firstly, the theory of empirical mode decomposition (EMD) is introduced, and the reconstructing and filtering algorithm of intrinsic mode functions (IMF) from EMD is given in this paper.

本文介绍了经验模态分解的方法与原理，给出了由经验模态分解产生的固有模态函数重构组合滤波器的原理与详细算法。

Empirical mode decomposition(EMD) is a signal processing technique to decompose data set into several intrinsic mode functions(IMF) by a sifting process.

经验模式分解（EMD）通过筛分过程将原始信号分解成若干个基本模式分量（IMF），可看作无需预设带宽的自适应高通滤波方法。
