    • Beyond Nyquist sampling: a cost-based approach 

      Özçelikkale, A.; Ozaktas, H. M. (Optical Society of America, 2013)
      A sampling-based framework for finding the optimal representation of a finite energy optical field using a finite number of bits is presented. For a given bit budget, we determine the optimum number and spacing of the ...
    • On the Capacity of Fading Channels With Amplitude-Limited Inputs 

      Elmoslimany, A.; Duman, T. M. (Institute of Electrical and Electronics Engineers Inc., 2016)
      We address the problem of finding the capacity of fading channels under the assumption of amplitude-limited inputs. Specifically, we show that if the fading coefficients have a finite support and the channel state information ...
    • Representation of optical fields using finite numbers of bits 

      Özçelikkale, A.; Ozaktas, H. M. (Optical Society of America, 2012-06-04)
      We consider the problem of representation of a finite-energy optical field, with a finite number of bits. The optical field is represented with a finite number of uniformly spaced finite-accuracy samples (there is a finite ...
