    • Fractional Fourier domains 

      Haldun M. Özaktaş; Aytür, O. (Elsevier BV, 1995-09)
      It is customary to define the time-frequency plane such that time and frequency are mutually orthogonal coordinates. Representations of a signal in these domains are related by the Fourier transform. We consider a continuum ...

    • Generalization of time-frequency signal representations to joint fractional Fourier domains 

      Durak, L.; Özdemir, A. K.; Arıkan, Orhan; Song, I. (IEEE, 2005-09)
      The 2-D signal representations of variables rather than time and frequency have been proposed based on either Hermitian or unitary operators. As an alternative to the theoretical derivations based on operators, we propose ...

    • Zaman-frekans dağılımı için çekirdek kestirimi 

      Deprem, Zeynel; Çetin, A. Enis (IEEE, 2015-05)
      Bu dokümanda çözünürlüğü yüksek ve çapraz terim içermeyen Cohen sınıfı bir Zaman-frekans (ZF) dağılımının, çekirdek kestirim yöntemi ile elde edilmesi tanıtılmaktadır. Çekirdek kestirimi, başlangıç taslak bir zaman-frekans ...
