Several papers have been published recently on the quasi-maximum likelihood (QML)
approach for the polynomial phase signals (PPS) parameter estimation. The QML is …

Analyzing the ocean acoustic environment is a tricky task. Background noise and variable
channel transmission environment make it complicated to implement accurate ship-radiated …

Underwater acoustic target recognition is an intractable task due to the complex acoustic
source characteristics and sound propagation patterns. Limited by insufficient data and …

Underwater acoustic target recognition is a challenging task owing to the intricate
underwater environments and limited data availability. Insufficient data can hinder the ability …

In the multifaceted marine environment, numerous factors affect the noise radiated by ships,
thereby weakening the traditional spectral characteristics and diminishing the spectrum's …

This paper investigates better time frequency representations of littoral water ambient noise
recorded at 30 meter of depth in Indian tropical water. Linear time frequency representations …

Cette thèse a pour but de définir et concevoir de nouvelles techniques de représentation
des signauxacoustiques sous-marins. Notre objectif est d'interpréter, reconnaître et identifier …

This paper proposes a new signal processing technique using time-frequency distribution
(TFD), namely S-transform (ST) for battery parameters estimation. Compared to other TFDs …
