In this paper, we have presented a novel variational method
for decomposing a signal into an ensemble of band-limited
intrinsic mode functions, that we call Variational Mode De-
composition, (VMD). In contrast to existing decomposition
models, like the empirical mode decomposition (EMD), we
refrain from modeling the individual modes as signals with
explicit IMFs. Instead, we replace the most recent definition
of IMFs, namely their characteristic description as AM-FM
signals, by the corresponding narrow-band property. Indeed,
we provide a formula that relates the parameters of the explicit
AM-FM descriptors to the estimated signal bandwidth.
