Abstract :
The fractional Fourier transform (FRFT) is a one-parametric generalization of the classical Fourier transform. Since it´s introduction in 1980ft, the FRFT has been found a lot of applications and used widely nowadays in signal processing. Space and spatial frequency domains are the special cases of the fractional Fourier domains. They correspond to the 0th and 1st fractional Fourier domains, respectively. In this paper, we briefly introduce the multi-parametrical FRFT and its fast algorithm.
