Noise-Assisted Multivariate Variational Mode Decomposition [PDF]

open access: yesICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021
The variational mode decomposition (VMD) is a widely applied optimization-based method, which analyzes non-stationary signals concurrently. Correspondingly, its recently proposed multivariate extension, i.e., MVMD, has shown great potentials in analyzing multichannel signals.

Multivariate Variational Mode Decomposition [PDF]

open access: yesIEEE Transactions on Signal Processing, 2019
In this paper, a generic extension of variational mode decomposition (VMD) algorithm for multivariate or multichannel data sets is presented. We first define a model for multivariate modulated oscillations that is based on the presence of a joint or common frequency component among all channels of input data.

Multivariate Nonlinear Sparse Mode Decomposition and Its Application in Gear Fault Diagnosis

open access: yesIEEE Access, 2021
Multi-channel signal has more abundant and accurate state characteristic information than single channel signal. How to separate fault characteristic information from the multi-channel signal is the key of fault diagnosis.

New achievements on daily reference evapotranspiration forecasting: Potential assessment of multivariate signal decomposition schemes

open access: yesEcological Indicators, 2023
Reference evapotranspiration (ETo) is a vital climate parameter affecting plants' water use. ETo can generate large deficits in soil moisture and runoff in different regions and seasons, leading to uncertainties in drought warning systems.
