A new look at the Empirical Mode Decomposition

2014Resumen
En este artículo se lleva a cabo una revisión de la EMD desde el punto de vista de las aplicaciones. Se abordan dos problemas importantes y las soluciones propuestas. In this paper a look into EMD from the application point of view is done. Two
important problems are faced and solutions proposed: a) the removal of false
components and b) the increase in number of IMFs and computational time
in long signals. To detect which IMFs are not presented in the original signal
we propose an algorithm based on the spectral inversion and correlation. For
decomposing very long signals a sequential sifting on segments of the signal
in a sliding window is proposed.
