      Noise enhanced detection in the restricted Bayesian framework 

      Bayram, Suat; Gezici, Sinan; Poor H.V. (IEEE, 2010)
      Effects of additive independent noise are investigated for sub-optimal detectors according to the restricted Bayes criterion. The statistics of optimal additive noise are characterized. Also, sufficient conditions for ...

      Optimal stochastic signaling for power-constrained binary communications systems 

      Goken, C.; Gezici, Sinan; Arıkan, Orhan (IEEE, 2010)
      Optimal stochastic signaling is studied under second and fourth moment constraints for the detection of scalar-valued binary signals in additive noise channels. Sufficient conditions are obtained to specify when the use ...

      Joint detection and decoding in the presence of prior information with uncertainty 

      Bayram, S.; Dulek, B.; Gezici, Sinan (Institute of Electrical and Electronics Engineers Inc., 2016)
      An optimal decision framework is proposed for joint detection and decoding when the prior information is available with some uncertainty. The proposed framework provides tradeoffs between the average inclusive error ...

      Noise benefits in joint detection and estimation problems 

      Akbay, A. B.; Gezici, Sinan (Elsevier, 2016)
      Adding noise to inputs of some suboptimal detectors or estimators can improve their performance under certain conditions. In the literature, noise benefits have been studied for detection and estimation systems separately. ...

      Noise enhanced M-ary composite hypothesis-testing in the presence of partial prior information 

      Bayram, S.; Gezici, Sinan (IEEE, 2010-12-06)
      In this correspondence, noise enhanced detection is studied for M-ary composite hypothesis-testing problems in the presence of partial prior information. Optimal additive noise is obtained according to two criteria, which ...

      Convexity properties of detection probability for noncoherent detection of a modulated sinusoidal carrier 

      Ozturk, C.; Dulek, B.; Gezici, Sinan (Institute of Electrical and Electronics Engineers, 2018)
      In this correspondence paper, the problem of noncoherent detection of a sinusoidal carrier is considered in the presence of Gaussian noise. The convexity properties of the detection probability are characterized with respect ...

      Optimal detector randomization for multiuser communications systems 

      Tutay, M. E.; Gezici, Sinan; Arıkan, Orhan (IEEE, 2013)
      Optimal detector randomization is studied for the downlink of a multiuser communications system, in which users can perform time-sharing among multiple detectors. A formulation is provided to obtain optimal signal amplitudes, ...

      Birleşik sezim ve kestirim sistemlerinin gürültü ile geliştirilmesi 

      Akbay, Abdullah Başar; Gezici, Sinan (IEEE, 2014-04)
      Belirli koşullar altında, optimal olmayan bazı sezici ve kestiricilerin performansını girdilerine gürültü ekleyerek geliştirmek mümkündür. Bu çalışmada, birleşik bir sezim ve kestirim sisteminin gürültü eklenerek geliştirilmesi ...

      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 ...

      Noise-enhanced M-ary hypothesis-testing in the minimax framework 

      Bayram, Suat; Gezici, Sinan (IEEE, 2009-09)
      In this study, the effects of adding independent noise to observations of a suboptimal detector are studied for M-ary hypothesis-testing problems according to the minimax criterion. It is shown that the optimal additional ...
