      On the optimality of stochastic signaling under an average power constraint 

      Göken, Çağrı; Gezici, Sinan; Arıkan, Orhan (IEEE, 2010-09-10)
      In this paper, stochastic signaling is studied for scalar valued binary communications systems over additive noise channels in the presence of an average power constraint. For a given decision rule at the receiver, the ...

      Noise enhanced detection in restricted Neyman-Pearson framework 

      Bayram, S.; Gültekin, San; Gezici, Sinan (IEEE, 2012-06)
      Noise enhanced detection is studied for binary composite hypothesis-testing problems in the presence of prior information uncertainty. The restricted Neyman-Pearson (NP) framework is considered, and a formulation is obtained ...

      Effects of channel state information uncertainty on the performance of stochastic signaling 

      Göken, Çağrı; Gezici, Sinan; Arıkan, Orhan (IEEE, 2011)
      In this paper, stochastic signaling is studied for power-constrained scalar valued binary communications systems in the presence of uncertainties in channel state information (CSI). First, it is shown that, for a given ...

      Stochastic signaling under second and fourth moment constraints 

      Göken, Çağrı; Gezici, Sinan; Arıkan, Orhan (IEEE, 2010)
      Stochastic signaling is investigated under second and fourth moment constraints for the detection of scalar-valued binary signals in additive noise channels. Sufficient conditions are derived to determine when the use of ...

      Stochastic signaling in the presence of channel state information uncertainty 

      Goken, C.; Gezici, Sinan; Arıkan, Orhan (Elsevier, 2013)
      In this paper, stochastic signaling is studied for power-constrained scalar valued binary communications systems in the presence of uncertainties in channel state information (CSI). First, stochastic signaling based on the ...

      Average fisher information optimization for quantized measurements using additive independent noise 

      Balkan, Gokce Osman; Gezici, Sinan (IEEE, 2010)
      Adding noise to nonlinear systems can enhance their performance. Additive noise benefits are observed also in parameter estimation problems based on quantized observations. In this study, the purpose is to find the optimal ...

      Optimal stochastic signal design and detector randomization in the Neyman-Pearson framework 

      Dülek, Berkan; Gezici, Sinan (IEEE, 2012-03)
      Power constrained on-off keying communications systems are investigated in the presence of stochastic signaling and detector randomization. The joint optimal design of decision rules, stochastic signals, and detector ...

      Detector randomization and stochastic signaling for minimum probability of error receivers 

      Dulek, B.; Gezici, Sinan (Institute of Electrical and Electronics Engineers, 2012)
      Optimal receiver design is studied for a communications system in which both detector randomization and stochastic signaling can be performed. First, it is proven that stochastic signaling without detector randomization ...

      Optimal stochastic parameter design for estimation problems 

      Soganci, H.; Gezici, Sinan; Arıkan, Orhan (Institute of Electrical and Electronics Engineers, 2012)
      In this study, the aim is to perform optimal stochastic parameter design in order to minimize the cost of a given estimator. Optimal probability distributions of signals corresponding to different parameters are obtained ...

      Convexity properties of outage probability under Rayleigh fading 

      Dülek, Berkan; Vanlı, N. Denizcan; Gezici, Sinan (IEEE, 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 ...
