Abstract EN
This paper proposes a new signal decomposition method that aims to decompose a multicomponent signal into monocomponent signal.
The main procedure is to extract the components with frequencies higher than a given bisecting frequency by three steps: (1) the generalized demodulation is used to project the components with lower frequencies onto negative frequency domain, (2) the Hilbert transform is performed to eliminate the negative frequency components, and (3) the inverse generalized demodulation is used to obtain the signal which contains components with higher frequencies only.
By running the procedure recursively, all monocomponent signals can be extracted efficiently.
A comprehensive derivation of the decomposition method is provided.
The validity of the proposed method has been demonstrated by extensive numerical analysis.
The proposed method is also applied to decompose the dynamic strain signal of a cable-stayed bridge and the echolocation signal of a bat.
