Coupled 2D-Fractional Wavelet Transform Rajakumar Roopkumar, Ramanathan Kamalakkannan, Ahmed Zayed Contemporary Mathematics Singapore, 2024 We introduce a new fractional wavelet transform using the convolution for the coupled fractional Fourier transform. We derive that the fractional wavelet transform satisfies all the expected properties such as Parseval identity, inversion formula, convolution theorem. We also characterize the range of the fractional wavelet transform on . Finally, we establish the uncertainty principle for the fractional wavelet transform.
On the extension of the coupled fractional Fourier transform and its properties R. Kamalakkannan, R. Roopkumar, A. Zayed Integral Transforms and Special Functions, 2022 The coupled fractional Fourier transform is a two-dimensional fractional Fourier transform that depends on two angles that are coupled in such a way that the transform parameters are and It generalizes the two-dimensional Fourier transform and it serves as useful tool in some applications in optics and signal processing. In this article we derive new properties of the transform, such as its additive property. We then extend some of them to and show that the transform is a unitary operator on
Short time coupled fractional fourier transform and the uncertainty principle Ramanathan Kamalakkannan, Rajakumar Roopkumar, Ahmed Zayed Fractional Calculus and Applied Analysis, 2021 In this paper, we introduce a short-time coupled fractional Fourier transform ( scfrft ) using the kernel of the coupled fractional Fourier transform ( cfrft ). We then prove that it satisfies Parseval’s relation, derive its inversion and addition formulas, and characterize its range on ℒ 2 (ℝ 2 ). We also study its time delay and frequency shift properties and conclude the article by a derivation of an uncertainty principle for both the coupled fractional Fourier transform and short-time coupled fractional Fourier transform.
Multidimensional fractional Fourier transform and generalized fractional convolution R. Kamalakkannan, R. Roopkumar Integral Transforms and Special Functions, 2020 In this paper, we prove inversion theorems and Parseval identity for the multidimensional fractional Fourier transform. Analogous to the existing fractional convolutions on functions of single variable, we also introduce a generalized fractional convolution on functions of several variables and we derive their properties including convolution theorem and product theorem for the multidimensional fractional Fourier transform.
