Noise and non-stationary components may result in false boundaries when empirical
wavelet transform (EWT) is applied to mode decomposition. In this paper, a revised method …

In this paper, an enhanced Empirical Wavelet Transform (EWT) approach based on
Synchroextracting Transform (SET) is proposed for time-varying system identification. When …

The use of the combination method of empirical mode decomposition (EMD) and wavelet
analysis is explored for the detection of changes in the structural response data. Firstly, we …

To overcome the inaccurate frequency band division in empirical wavelet transform (EWT)
induced by high noise and modulation edge band, this study proposes an improved EWT …

There are various signal decomposition methods, but none of them is satisfactory and all
have their own drawbacks. It is worth exploring a new signal decomposition approach with …

A synchrosqueezed wavelet transform combined by wavelet analysis and time–frequency
reallocation method was recently developed to improve the quality of time–frequency …

This paper proposes an enhanced vibration decomposition approach based on analytical
mode decomposition (AMD) and multisynchrosqueezing transform (MSST). Although AMD …

This paper proposes an improved Empirical Wavelet Transform (EWT) approach for
structural operational modal identification based on measured dynamic responses of …

Frequency domain decomposition (FDD) has been widely used for output-only system
identification due to ambient excitations in the frequency domain. FDD, however, usually …

The determination of accurate global and local modal information is a crucial step for any
structural model updating process. Existing modal extraction methods can extract global …
