The empirical mode decomposition and the Hilbert spectrum for nonlinear and non-stationary time series analysis

PROCEEDINGS OF THE ROYAL SOCIETY A-MATHEMATICAL PHYSICAL AND ENGINEERING SCIENCES, 454(1971), 903–995.

By: N. Huang*, Z. Shen*, . Long *, M. Wu *, H. Shih*, Q. Zheng *, N. Yen*, C. Tung n, H. Liu*

author keywords: non-stationary time series; nonlinear differential equations; frequency-time spectrum; Hilbert spectral analysis; intrinsic time scale; empirical mode decomposition
MeSH headings : Air Pollutants / analysis; Algorithms; Civil Defense; Environmental Monitoring / methods; Signal Processing, Computer-Assisted
TL;DR: The main conceptual innovations are the introduction of ‘intrinsic mode functions’ based on local properties of the signal, which make the instantaneous frequency meaningful; and the introducing of the instantaneous frequencies for complicated data sets, which eliminate the need for spurious harmonics to represent nonlinear and non-stationary signals.
