Asian Research Journal of MathematicsIn this paper, we introduce the characterization of compactness of the coupled fractional Fourier transform (CFrFT). Few results on compactness of pseudo-differential operators (P.D.O) connected with CFrFT are investigated.

Asian Research Journal of MathematicsIn this research work, the symbol class Λ (R×R×R×R) is discussed. Then, we give the fundamental properties of this symbol class. Furthermore, the Pseudo-differential operators (p.d.o.) A(x, y,D′x,y) and A(x, y,D′x,y) involving the coupled fractional Fourier transform (CFrFT) Fα1,α2 associated with symbol classes are defined.

Asian Research Journal of MathematicsIn this manuscript, some results on the Pseudo-differential operators (p.d.o.) L(x, y,D′ x,y) and L(x, y,D′ x,y) are found by using semi-norms and norms in Herbitian Spaces, a set of compact operators and L2(R×R) with the symbol classes Λ(R × R × R × R).

Uncertainty principles associated with the short time quaternion coupled fractional Fourier transform [PDF]
, 2023 In this paper, we extend the coupled fractional Fourier transform of a complex valued functions to that of the quaternion valued functions on $\mathbb{R}^4$ and call it the quaternion coupled fractional Fourier transform (QCFrFT).

Radar matched filtering using the fractional fourier transform [PDF]
, 2010 -A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be ...
