- W2026271794 abstract "This paper describes an approach for decomposing a signal into the sum of an oscillatory component and atransient component. The method uses a newly developed rational-dilation wavelet transform (WT), a self-invertingconstant-Q transform with an adjustable Q-factor (quality-factor). We propose that the oscillatorycomponent be modeled as signal that can be sparsely represented using a high Q-factor WT; likewise, wepropose that the transient component be modeled as a piecewise smooth signal that can be sparsely representedusing a low Q-factor WT. Because the low and high Q-factor wavelet transforms are highly distinct (having lowcoherence), morphological component analysis (MCA) successfully yields the desired decomposition of a signalinto an oscillatory and non-oscillatory component. The method, being non-linear, is not constrained by the limitsof conventional LTI filtering." @default.
