It is quite challenging for the quadratic time-frequency distribution (QTFD) to analyze the
multi-component linear frequency modulation (MC-LFM) signals due to its inevitable cross …

Frequency-modulated (FM) signals, prevalent across various applied disciplines, exhibit
time-dependent frequencies and a multicomponent nature necessitating the utilization of …

The time-frequency analysis of nonstationary multicomponent linear frequency modulation
(LFM) signals is still a challenging task due to their cross-term interferences. In this paper, a …

The primary purpose of this letter is to propose a low complexity estimator of the hyperbolic
frequency modulated (HFM) signal. A novel approximation expression for the spectrum of …
