The Multidimensional Quadratic Phase Fourier Transform: Theoretical Analysis and Applications
摘要
The quadratic phase Fourier transform (QPFT) is a generalization of several well known integral transforms, including the linear canonical transform (LCT), fractional Fourier transform (FrFT), and Fourier transform (FT). This paper introduces the multidimensional QPFT and investigates its theoretical properties, including Parseval’s identity and inversion theorems. Also, multidimensional convolution is proposed for QPFT in the multidimensional setting. Additionally, Boas type theorem for the multidimensional QPFT is established. As applications, multidimensional multiplicative filter design and the solution of multidimensional integral and differential equations using the proposed convolution operation are explored.
