Parameterized Local Maximum Synchrosqueezing Transform and its Application in Engineering Vibration Signal Processing

open access: yesIEEE Access, 2021
The time-frequency (TF) analysis (TFA) method is an effective tool for analyzing the time-variant features of non-stationary signals. Synchrosqueezing transform (SST) is a promising TFA method that has recently shown its usefulness in a wide range of ...

The monogenic synchrosqueezed wavelet transform: a tool for the decomposition/demodulation of AM–FM images [PDF]

open access: yes, 2015
The synchrosqueezing method aims at decomposing 1D functions into superpositions of a small number of “Intrinsic Modes”, supposed to be well separated both in time and frequency.

Research on Fault Diagnosis of Rolling Bearing based on Synchrosqueezing Extracting Transform

open access: yesJixie chuandong, 2021
Rolling bearings are important components of large machinery and play a very important role. When the bearing fails, if not repaired or replaced them in time, it will seriously affect the life of the equipment.

Fuzzy determination of informative frequency band for bearing fault detection [PDF]

open access: yes, 2016
Detecting early faults in rolling element bearings is a crucial measure for the health maintenance of rotating machinery. As faulty features of bearings are usually demodulated into a high-frequency band, determining the informative frequency band (IFB ...

Intrinsic synchrosqueezing analysis on micro‐Doppler features for small unmanned aerial vehicles identification with dual‐channel radar

open access: yesIET Microwaves, Antennas & Propagation, 2021
The micro‐Doppler (m‐D) effect depends on the rotation of rotor blades in addition to the translation of the platform. Thus it is a characteristic for identifying small unmanned aerial vehicles (UAVs). However, compared with the Doppler signal induced by
