Synchro-Transient-Extracting Transform for the Analysis of Signals with Both Harmonic and Impulsive Components

no code implementations2 Jun 2023 Yunlong Ma, Gang Yu, Tianran Lin, Qingtang Jiang

This allows the technique to generate an energy-concentrated TF representation for both harmonics and impulses in the signal.

Direct Signal Separation Via Extraction of Local Frequencies with Adaptive Time-Varying Parameters

no code implementations5 Oct 2020 Lin Li, Charles K. Chui, Qingtang Jiang

In this paper, we propose an adaptive signal separation operation (ASSO) for effective and accurate separation of a single-channel blind-source multi-component signal, via introducing a time-varying parameter that adapts locally to IFs and using linear chirp (linear frequency modulation) signals to approximate components at each time instant.

A Chirplet Transform-based Mode Retrieval Method for Multicomponent Signals with Crossover Instantaneous Frequencies

no code implementations4 Oct 2020 Lin Li, Ningning Han, Qingtang Jiang, Charles K. Chui

We use the chirplet transform (CT) to represent a multicomponent signal in the three-dimensional space of time, frequency and chirp rate and introduce a CT-based signal separation scheme (CT3S) to retrieve modes.

Analysis of Adaptive Synchrosqueezing Transform with a Time-varying Parameter

no code implementations22 Aug 2020 Jian Lu, Qingtang Jiang, Lin Li

The WSST with a time-varying parameter, called the adaptive WSST, was introduced very recently in the paper "Adaptive synchrosqueezing transform with a time-varying parameter for non-stationary signal separation".
