Fractional fourier transforms of hypercomplex signals [PDF]

open access: greenSignal, Image and Video Processing, 2012
An overview is given to a new approach for obtaining generalized Fourier transforms in the context of hypercomplex analysis (or Clifford analysis). These transforms are applicable to higher-dimensional signals with several components and are different ...

The fractional Clifford-Fourier transform [PDF]

open access: yesComplex Analysis and Operator Theory, 2012
In this paper, a fractional version of the Clifford-Fourier transform is introduced, depending on two numerical parameters. A series expansion for the kernel of the resulting integral transform is derived.

Tunable fractional Fourier transform implementation of electronic wave functions in atomically thin materials [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2018
A tunable fractional Fourier transform of the quantum wave function of electrons satisfying either the Schrödinger or the Dirac equation can be implemented in an atomically thin material by a parabolic potential distribution applied on a direction ...

The minimality of mean square error in chirp approximation using fractional fourier series and fractional fourier transform [PDF]

open access: yesScientific Reports, 2022
Chirps are familiar in nature, have a built-in resistance to noise and interference, and are connected to a wide range of highly oscillatory processes.

Discrete fractional Fourier transform [PDF]

open access: green1996 IEEE International Symposium on Circuits and Systems. Circuits and Systems Connecting the World. ISCAS 96, 2002
The continuous fractional Fourier transform (FRFT) represents a rotation of signal in time-frequency plane, and it has become an important tool for signal analysis. A discrete version of fractional Fourier transform has been developed but its results do not match those of continuous case.

Uncertainty principles for coupled fractional Wigner–Ville distribution [PDF]

open access: yesRoyal Society Open Science
The coupled fractional Wigner–Ville distribution is a more general version of the fractional Wigner–Ville distribution. Main properties including boundedness, Moyal’s formula and inversion formula are studied in detail for the transformation ...

A New LFM-Signal Detector Based on Fractional Fourier Transform [PDF]

open access: goldEURASIP Journal on Advances in Signal Processing, 2010
A new LFM-signal detector formulated by the integration of the 4th-power modulus of the fractional Fourier transform is proposed. It has similar performance to the modulus square detector of Radon-ambiguity transform because of the equivalence ...
