Based on numerical experiments on white noise using the empirical mode decomposition (EMD) method, we find empirically that the EMD is effectively a dyadic filter, the intrinsic mode function (IMF) components are all normally distributed, and the Fourier spectra of the IMF components are all identical and cover the same area on a semi–logarithmic period scale. Expanding from these empirical findings, we further deduce that the product of the energy density of IMF and its corresponding averaged…

The slope of the scaling exponent is used as the threshold for EMD based denoising and IMFs with lower slope than the threshold are assumed to be noisy oscillations and excluded in the reconstruction step.

Signal Denoising Using Empirical Mode Decomposition and Higher Order Statistics

Experimental results prove the applicability of EMD-HOS, which outperforms similar denoising techniques based on Wavelets for the most types of test signals.

Ensemble Empirical Mode Decomposition: a Noise-Assisted Data Analysis Method

The effect of the added white noise is to provide a uniform reference frame in the time–frequency space; therefore, the added noise collates the portion of the signal of comparable scale in one IMF.

Noise filtering using Empirical Mode Decomposition

In this paper a noise filtering method using the empirical mode decomposition (EMD) is proposed and a new criterion is proposed to determine the IMF after which the energy distribution of the important structures of the signal overcomes that of the noise and the high frequency components of the signals.

A De-noising Scheme Based on the Null Hypothesis of Intrinsic Mode Functions

The statistical properties of IMFs, produced by a range of signal distributions, are examined and the efficacy of the proposed method as compared to other EMD-based de-noising techniques is demonstrated.

On the Filtering Properties of the Empirical Mode Decomposition

This paper conjecture that, as the (pre-assigned and fixed) sifting number is changed from a small number to infinity, the EMD corresponds to filter banks with a filtering ratio that changes accordingly from 2 (dyadic) to 1; the filter window does not narrow accordingly, asThe siftingNumber increases.

A Criterion for Selecting Relevant Intrinsic Mode Functions in Empirical Mode Decomposition

A stringent threshold by which relevant IMFs are distinguished from IMFs that may have been generated by numerical errors is established, dependent on the correlation coefficient between the IMFs and the original signal.

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.

Empirical Mode Decomposition-Based Hierarchical Multiresolution Analysis for Suppressing Noise

This paper proposes a strategy for suppressing noise via empirical mode decomposition (EMD)-based hierarchical multiresolution analysis that can extract information from more than one level of decomposition to reconstruct the denoised signal compared to only one level in the conventional EMD-based denoising method.

A new method for analysing nonlinear and non-stationary data has been developed. The key part of the method is the ‘empirical mode decomposition’ method with which any complicated data set can be

Empirical mode decomposition as a filter bank

It turns out that EMD acts essentially as a dyadic filter bank resembling those involved in wavelet decompositions, and the hierarchy of the extracted modes may be similarly exploited for getting access to the Hurst exponent.
