empirical data decomposition

The use of empirical mode decomposition (EMD) method and wavelet analysis in combination is explored for the detection of changes in the structural response data from structural damage diagnosis.

采用经验模式分解(EMD)与小波分析相结合的方法探讨结构响应数据信号，进行建筑结构损伤检测诊断。

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。

A new scheme named Many-knot Empirical Mode decomposition (MEMD) of data decomposition for non-stationary data analysis is presented in this paper.

依据多结点样条函数插值理论，定义了模式函数，给出了数据分解过程。
