Singular spectrum analysis (SSA) is a signal decomposition technique that aims at
expanding signals into interpretable and physically meaningful components (eg, sinusoids …

The vehicle and bridge responses in a vehicle-bridge interaction (VBI) system have been
widely studied with some aiming at the bridge health monitoring. The extraction of bridge …

This paper considers the analysis of impulsive-like signals whose time-frequency ridge
curves are nearly perpendicular to the time axis. Although the instantaneous frequency of …

This paper proposes an intelligent diagnosis method for rotating machinery faults based on
improved variational mode decomposition (IVMD) and CNN to process the rotating …

Since decades past, time–frequency (TF) analysis has demonstrated its capability to
efficiently handle non-stationary multi-component signals which are ubiquitous in a large …

This paper addresses the problem of efficiently jointly representing a non-stationary
multicomponent signal in time and frequency. We introduce a novel enhancement of the …

This article introduces the second-order transient-extracting transform (TET2) to extract
transient components from a nonstationary signal. Different from the traditional transient …

The article describes algorithms for the retrieval of linear frequency modulated (LFM) pulses
from a received signal which is corrupted by noise and multipath reflections from ground and …

This paper addresses the problem of estimating the instantaneous frequency (IF) and
amplitude of the modes composing a non-stationary multicomponent signal in the presence …

The time-frequency (TF) analysis always plays a major role in signal processing. In this
letter, we propose a novel TF analysis method called the second-order adaptive …
