Asymptotic analysis of synchrosqueezing transform -- toward statistical inference with nonlinear-type time-frequency analysis

, 2023
We provide a statistical analysis of a tool in nonlinear-type time-frequency analysis, the synchrosqueezing transform (SST), for both the null and non-null cases.

High-Order Time-Reassigned Synchrosqueezing Transform and Its Application in Tight Sandstone Gas Reservoir

IEEE Access
Time-frequency analysis (TFA) can provide relevant information about subsurface reservoirs, which is essential in reservoir identification. Traditional TFA methods are limited by resolution, resulting in unreliable seismic interpretation.

ULTRASONIC SIGNAL FEATURE EXTRACTION METHOD BASED ON GENERAL CROSS-VALIDATION THRESHOLDING IN SYNCHROSQUEEZING WAVELET DOMAIN

Jixie qiangdu, 2020
Using ultrasonic non-destructive testing technology,when detecting the surface crack of the shaft,the micro crack echo signal is often covered by various noises,which causes the crack to be unrecognizable and positioned. In order to solve this problem,in

Enhancing Time-Frequency Concentration and Accuracy Using an Improved Time-Frequency Synchrosqueezing Transform

The synchrosqueezing transform (SST) imp- roves the readability of time-frequency representation (TFR). The time-frequency multisqueezing transform (TFMST) is the most advanced SST method to date.
