Empirical mode decomposition (EMD) has recently been pioneered by Huang et al. for adaptively representing nonstationary signals as sums of zero-mean amplitude modulation frequency modulation components. In order to better understand the way EMD behaves in stochastic situations involving broadband noise, we report here on numerical experiments based on fractional Gaussian noise. In such a case, it turns out that EMD acts essentially as a dyadic filter bank resembling those involved in wavelet…

Empirical Mode Decompositions as Data-Driven Wavelet-like Expansions

The experimental spectral analysis and statistical characterization of the obtained modes reveal an equivalent filter bank structure which shares most properties of a wavelet decomposition in the same context, in terms of self-similarity, quasi-decorrelation and variance progression.

Application of Empirical Mode Decomposition in Denoising a Speech Signal

This paper attempts to review and summarize the use of Empirical mode decomposition (EMD) for denoising a speech signal. EMD, introduced by Huang et al in 1998 gives time-frequency representation of

Absolute value Empirical Mode Decomposition

The A-EMD approach can detect a new set of Intrinsic Mode Functions, which clearly present the location of the wave peaks and can quickly detect the jump points for the jump signals.

Hybrid wavelet-Hilbert-Huang spectrum analysis

Empirical mode decomposition (EMD) is a new method pioneered by Huang et al. for non-linear and non-stationary signal analysis. Signals are adaptively decomposed into several zero-mean amplitude

Iterative Filtering as an Alternative Algorithm for Empirical Mode Decomposition

This paper proposes an alternative algorithm for EMD based on iterating certain filters, such as Toeplitz filters, which yields similar results as the more traditional sifting algorithm, and can be rigorously proved.

It is found that, similarly to EMD, MEMD also essentially acts as a dyadic filter bank on each channel of the multivariate input signal, but better aligns the corresponding intrinsic mode functions from different channels across the same frequency range which is crucial for real world applications.

EMD Equivalent Filter Banks, from Interpretation to Applications

Huang's data-driven technique of empirical mode decomposition is given a filter bank interpretation from two complementary perspectives and a stochastic approach shows the spontaneous emergence of an equivalent dyadic filter bank structure when EMD is applied to the versatile class of fractional Gaussian noise processes.

Enhanced Empirical Mode Decomposition

Bandpass enhanced EMD is applied to a bat chirp signal and the fundamental, the first, second, and part of the third harmonic are expressed, demonstrating the improved sensitivity of this method over the standard HHT approach.

This paper describes a new technique, called the empirical mode decomposition (EMD), for adaptively representing nonstationary signals as sums of zero-mean AM-FM components that allows the analysis of frequency composition of one-dimensional signals.

Fast ensemble empirical mode decomposition for speech-like signal analysis using shaped noise addition

The experimental results show that both pink noise and brown noise outperform the white noise in terms of computation for the EEMD of speech-like signal, and the signal-spectrum-dependent noise is able to effectively randomize the targeted signal in time domain, and then significantly save the superfluous calculation around the corresponding energy-free frequencies.
