Relations between Gabor transforms and fractional Fourier transforms and their applications for signal processing

SC Pei, JJ Ding - IEEE Transactions on Signal Processing, 2007 - ieeexplore.ieee.org
Many useful relations between the Gabor transform (GT) and the fractional Fourier transform
(FRFT) have been derived. First, we find that, like the Wigner distribution function (WDF), the …

Repeated filtering in consecutive fractional Fourier domains and its application to signal restoration
