    • Adaptive filtering approaches for non-Gaussian stable processes 

      Arıkan, Orhan; Belge, Murat; Çetin, A. Enis; Erzin, Engin (IEEE, 1995-05)
      A large class of physical phenomenon observed in practice exhibit non-Gaussian behavior. In this paper, α-stable distributions, which have heavier tails than Gaussian distribution, are considered to model non-Gaussian ...
    • The discrete fractional Fourier transformation 

      Arıkan, Orhan; Kutay, M. Alper; Özaktaş, Haldun M.; Akdemir, Özer Koray (IEEE, 1996)
      Based on the fractional Fourier transformation of sampled periodic functions, the discrete form of the fractional Fourier transformation is obtained. It is found that only for a certain dense set of fractional orders such ...
    • Optimal filtering in fractional Fourier domains 

      Kutay, M. Alper; Onural, Levent; Özaktaş Haldun M.; Arıkan, Orhan (IEEE, 1995)
      The ordinary Fourier transform is suited best for analysis and processing of time-invariant signals and systems. When we are dealing with time-varying signals and systems, filtering in fractional Fourier domains might allow ...
    • Theoretical investigation on exact blind channel and input sequence estimation 

      Özdemir, A. K.; Arıkan, Orhan (IEEE, Piscataway, NJ, United States, 1999)
      Recent work on fractionally spaced blind equalizers have shown that it is possible to exactly identify the channel and its input sequence from the noise-free channel outputs. However, the obtained results are based on a ...
