Vibration Event Recognition Using SST-Based Φ-OTDR System
Sensors, 2023 We propose a method based on Synchrosqueezing Transform (SST) for vibration event analysis and identification in Phase Sensitive Optical Time-Domain Reflectometry (Φ-OTDR) systems.

Spectral analysis for nonstationary audio [PDF]
, 2018 A new approach for the analysis of nonstationary signals is proposed, with a focus on audio applications. Following earlier contributions, nonstationarity is modeled via stationarity-breaking operators acting on Gaussian stationary random signals.

Synchrosqueezing-based Transform and its Application in Seismic Data Analysis [PDF]
Iranian Journal of Oil & Gas Science and Technology, 2015 Seismic waves are non-stationary due to its propagation through the earth. Time-frequency transforms are suitable tools for analyzing non-stationary seismic signals.

An Improved Multi-Ridge Extraction Method Based on Differential Synchro-Squeezing Wavelet Transform
IEEE Access, 2021 It is very important to accurately extract the instantaneous frequency (IF) of complex non-stationary signals, so the signal processing methods based on IF are widely used in engineering.

Synchrosqueezing-based Recovery of Instantaneous Frequency from Nonuniform Samples
, 2011 We propose a new approach for studying the notion of the instantaneous frequency of a signal. We build on ideas from the Synchrosqueezing theory of Daubechies, Lu and Wu and consider a variant of Synchrosqueezing, based on the short-time Fourier ...
