Variational Mode Decomposition

IEEE Transactions on Signal Processing, 2014
During the late 1990s, Huang introduced the algorithm called Empirical Mode Decomposition, which is widely used today to recursively decompose a signal into different modes of unknown but separate spectral bands. EMD is known for limitations like sensitivity to noise and sampling. These limitations could only partially be addressed by more mathematical

Identification of electromechanical oscillatory modes based on variational mode decomposition

Electric Power Systems Research, 2019
Abstract This paper introduces Variational Mode Decomposition (VMD) to identify electromechanical oscillatory modes in power systems. The identification process is based on the time-frequency analysis of nonlinear signals which arise after a large disturbance.

Diffraction separation by variational mode decomposition

Geophysical Prospecting, 2021
ABSTRACTDiffracted wavefields with superior illumination encode key geologic information about small‐scale geologic discontinuities or inhomogeneities in the subsurface and thus possess great potential for high‐resolution imaging. However, the weak diffracted wavefield is easily masked by the dominant reflected data.

Generalized Variational Mode Decomposition: A Multiscale and Fixed-Frequency Decomposition Algorithm

IEEE Transactions on Instrumentation and Measurement, 2021
To overcome the limitations of variational mode decomposition (VMD) algorithm that its frequency scales and spectrum positions cannot be flexibly adjusted to decompose signals as required, a generalized VMD (GVMD) was proposed. This article addresses the fundamental theory of GVMD. In order to highlight the local characteristics of the signal much more

Hierarchical decomposition based on a variation of empirical mode decomposition

Signal, Image and Video Processing, 2016
Adaptive methods of signal analysis have proved a very useful tool for analysis of non-stationary signals. This is due to the ability of these methods to adapt to the local structures of the signals being analysed, as these methods are not constrained by a fixed basis.

Bayesian Dynamic Mode Decomposition with Variational Matrix Factorization

Proceedings of the AAAI Conference on Artificial Intelligence, 2021
Dynamic mode decomposition (DMD) and its extensions are data-driven methods that have substantially contributed to our understanding of dynamical systems. However, because DMD and most of its extensions are deterministic, it is difficult to treat probabilistic representations of parameters and predictions.

Enhancement of variational mode decomposition with missing values

Signal Processing, 2018
A new variational mode decomposition that efficiently handles missing data is proposed.A practical algorithm that reflects the adjustment of the missing sample effects under the framework of VMD algorithm is developed.Proposed method can be applicable to analyze various kind of signals through wavelet transform.

Radiometric identification using variational mode decomposition

Computers & Electrical Engineering, 2019
Abstract Radiometric Identification (RAI) is the identification of wireless devices through their Radio Frequency (RF) emissions. In recent years, the research community has investigated it applying different methods and sets of statistical features extracted from the digitized RF emissions.
