    • Convexity properties of outage probability under Rayleigh fading 

      Dülek, B.; Vanli, N.D.; Gezici, S. (2012)
      In this paper, convexity properties of outage probability are investigated under Rayleigh fading for an average power-constrained communications system that employs maximal-ratio combining (MRC) at the receiver. By studying ...
    • Time-delay estimation in dispersed spectrum cognitive radio systems 

      Kocak, F.; Celebi, H.; Gezici, S.; Qaraqe, K. A.; Arslan, H.; Poor, H. V. (SpringerOpen, 2010)
      Time-delay estimation is studied for cognitive radio systems, which facilitate opportunistic use of spectral resources. A two-step approach is proposed to obtain accurate time-delay estimates of signals that occupy multiple ...
