    • Joint precoder and artificial noise design for MIMO wiretap channels with finite-alphabet inputs based on the cut-off rate 

      Aghdam, S. R.; Duman, T. M. (Institute of Electrical and Electronics Engineers Inc., 2017)
      We consider precoder and artificial noise (AN) design for multi-antenna wiretap channels under the finite-alphabet input assumption. We assume that the transmitter has access to the channel coefficients of the legitimate ...
    • Low complexity precoding for MIMOME wiretap channels based on cut-off rate 

      Aghdam, Sina Rezaei; Duman, Tolga M. (IEEE, 2016)
      We propose a low complexity transmit signal design scheme for achieving information-theoretic secrecy over a MIMO wiretap channel driven by finite-alphabet inputs. We assume that the transmitter has perfect channel state ...
    • On the origin of polar coding 

      Arıkan, E. (Institute of Electrical and Electronics Engineers Inc., 2016)
      Polar coding was conceived originally as a technique for boosting the cutoff rate of sequential decoding, along the lines of earlier schemes of Pinsker and Massey. The key idea in boosting the cutoff rate is to take a ...
    • Secure multi-antenna transmission with finite-alphabet signaling 

      Aghdam, Sina Rezaei (Bilkent University, 2018-01)
      With the ever-growing demand for services that rely on transmission over wireless networks, a challenging issue is the security of the transmitted information. Due to its open nature, wireless communications is prone to ...
