A sampling limit for the empirical mode decomposition [PDF]
, 2005 The aim of this paper is to investigate the effect of sampling on the empirical mode decomposition (EMD). To this end, an experiment utilising linear frequency modulated (LFM) signals was used to simulate different sampling rates.

Image analysis by bidimensional empirical mode decomposition [PDF]
, 2003 International audienceRecent developments in analysis methods on the non-linear and non-stationary data have received large attention by the image analysts. In 1998, Huang introduced the empirical mode decomposition (EMD) in signal processing.

Signal prediction based on empirical mode decomposition and artificial neural networks
Geodesy and Geodynamics, 2012 In view of the usefulness of Empirical Mode Decomposition (EMD), Artificial Neural Networks (ANN), and Most Relevant Matching Extension (MRME) methods in dealing with nonlinear signals, we propose a new way of combining these methods to deal with signal ...

Fault Diagnosis of Wind-turbine Gearboxes based on Fourier Decomposition Method
Jixie chuandong, 2018 The Empirical Mode Decomposition （EMD）,as an empirical method,lacks rigorous theoretical proof. For this reason,EMD in practical application is confronted by many problems,which make EMD hard to extract fault features from vibration data of complex wind ...
