Abstract
In this paper, we define the Wigner-Ville distribution function (WVDF) and corre-
sponding Weyl operator in the linear canonical transform (LCT) domain. Further, we
examine Moyle identity for the WVDF and investigate some of its properties. More-
over, we discuss the boundedness and compactness of Weyl operator on the Lpspace

1 Introduction
In quantum mechanics, the Wigner-Weyl transform is the invertible mapping between
functions in the quantum phase space formulation and Hilbert space operators in
the Schrödinger picture. This mapping was originally devised by Hermann Weyl in
1927 on an attempt to map symmetrized classical phase space functions to operators in
quantum mechanics, a procedure known as Weyl quantization [1]. But the map merely
amounts to a change of representation within quantum mechanics inspite of classical
to quantum quantities [2].

... Similar to the main component of the signal, the linear combination of kernel function can represent it sparsely. The second one is quadratic time-frequency distribution, such as the Wigner-Ville distribution (Zcza et al., 2021;Kumar and Prasad, 2022). Without the interference of the window function, this method avoids constraints between time resolution and frequency resolution. ...

A line spectrum presents the form of a narrow-band time-varying signal due to Doppler effect when the single hydrophone node observes flight-radiated noise. The modulation law of the time-varying signal contains a large number of feature information of moving targets, which can be used for detection and classification. This paper studies the possibility of using instantaneous frequency measurements from the hydrophone node to improve the precision of the flight parameter estimates when the source spectrum contains a harmonic line of constant frequency. First of all, we build up and analyze the underwater sound field excited by the aircraft using the ray theory model; then the Doppler shift in the two isospeed media, which is caused by the aircraft, is established; finally, a robust time–frequency transform describes the time–frequency distribution of the received signal, and a geometric approach solves the flying parameters.

For our analysis of the Gibbs measure, we use a one-step renormalization approach and semiclassical methods to study the eigenvalue-spacing of an auxiliary Schrödinger operator.

In this paper, we define the windowed‐Mehler–Fock transform and introduce the corresponding Weyl transform. Further, we examine the boundedness of windowed‐Mehler–Fock transform in Lebesgue space and establish some of its fundamental properties. Also, we give the criteria of boundedness and compactness of Weyl transform in Lebesgue space.

The linear canonical transform (LCT) is a powerful tool for signal processing and optics. It is, therefore, worthwhile and interesting to consider the Wigner-Ville distribution (WVD) in the LCT domain. In this paper, we propose a new definition for the WVD associated with the instantaneous autocorrelation function in the LCT domain, which we name as WL, and also obtain some properties of WL. As a further generalization of WL, a new definition for the WVD associated with the offset linear canonical transform (OLCT) is given. Finally, we have achieved some applications of the new WVD in the LCT and OLCT domain to verify the derived theory.

The linear canonical transform is shown to be one of the most powerful tools for nonstationary signal processing. Based on the properties of the linear canonical transform and the classical Wigner-Ville transform, this paper investigates the Wigner-Ville distribution in the linear canonical transform domain. Firstly, unlike the classical Wigner-Ville transform, a new definition of Wigner-Ville distribution associated with the linear canonical transform is given. Then, the main properties of the newly defined Wigner-Ville transform are investigated in detail. Finally, the applications of the newly defined Wigner-Ville transform in the linear-frequency-modulated signal detection are proposed, and the simulation results are also given to verify the derived theory.

The main objective of this paper is to enrich the theoretical system of the linear canonical Fourier transform (LCFT) by introducing the canonical potential Jm,A and corresponding Lp-Sobolev space. Moreover, the Schwartz-type space SA is introduced. Further, pseudo-differential operator (PDO) is defined and obtained its another integral representation. The Lp-boundedness result for the pseudo-differential operator associated with the LCFT is discussed. Some applications of Sobolev-type spaces HAm,p and HAm,p are given.

Integral transforms are among the main mathematical methods for the solution of equations describing physical systems, because, quite generally, the coupling between the elements which constitute such a system-these can be the mass points in a finite spring lattice or the continuum of a diffusive or elastic medium-prevents a straightforward "single-particle" solution. By describing the same system in an appropriate reference frame, one can often bring about a mathematical uncoupling of the equations in such a way that the solution becomes that of noninteracting constituents. The "tilt" in the reference frame is a finite or integral transform, according to whether the system has a finite or infinite number of elements. The types of coupling which yield to the integral transform method include diffusive and elastic interactions in "classical" systems as well as the more common quantum-mechanical potentials. The purpose of this volume is to present an orderly exposition of the theory and some of the applications of the finite and integral transforms associated with the names of Fourier, Bessel, Laplace, Hankel, Gauss, Bargmann, and several others in the same vein. The volume is divided into four parts dealing, respectively, with finite, series, integral, and canonical transforms. They are intended to serve as independent units. The reader is assumed to have greater mathematical sophistication in the later parts, though.

We have already used average values of position and momentum of a particle and seen that we can get the average value of an observable F [represented by an operator function F̂(x,p̂)] in a state ψ by $$ \left\langle {\hat F} \right\rangle = \bar F = \int {\psi *\hat F\psi dV,} $$ (4.1) where F̂ is the operator which is somehow related to F. In a first approach we are now going to deal with operators from a more general point of view. After this we shall determine a class of operators which is very important in quantum mechanics.

Although time–frequency analysis of signals had its origin almost 50 years ago, there has been major development of the time–frequency distributions approach in the last two decades. The basic idea of the method is to develop a joint function of time and frequency, known as a time–frequency distribution, that can describe the energy density of a signal simultaneously in both time and frequency. In principle, the time–frequency distributions characterize phenomena in a two-dimensional time–frequency plane. Basically, there are two kinds of time–frequency representations. One is the quadratic method covering the time–frequency distributions, and the other is the linear approach including the Gabor transform, the Zak transform, and the wavelet transform analysis.
