    • Optimal filtering in fractional Fourier domains 

      Kutay, M. A.; Özaktaş, Haldun M.; Arıkan, Orhan (Institute of Electrical and Electronics Engineers, 1997-05)
      For time-invariant degradation models and stationary signals and noise, the classical Fourier domain Wiener filter, which can be implemented in O(N log N) time, gives the minimum mean-square-error estimate of the original ...
