A Bayesian approach to respiration rate estimation via pulse-based ultra-wideband signals
(IEEE, 2009)In this paper, theoretical limits on estimation of respiration rates via pulse-based ultra-wideband (UWB) signals are studied in the presence of prior information about respiration related signal parameters. First, a ... -
Convexity properties of outage probability under Rayleigh fading
(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 ... -
Effects of additional independent noise in binary composite hypothesis-testing problems
(IEEE, 2009-09)Performance of some suboptimal detectors can be improved by adding independent noise to their observations. In this paper, the effects of adding independent noise to observations of a detector are investigated for binary ... -
Effects of channel state information uncertainty on the performance of stochastic signaling
(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 ... -
Low-order controller design for haptic systems under delayed feedback
(2012)In this paper, we consider PD controller design for haptic systems under delayed feedback. More precisely, we present a complete stability analysis of a haptic system where local dynamics are described by some second-order ... -
On the optimality of stochastic signaling under an average power constraint
(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 ... -
Optimal stochastic parameter design for estimation problems
(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 ... -
Stochastic resonance in binary composite hypothesis-testing problems in the Neyman-Pearson framework
(Elsevier, 2012-02-20)Performance of some suboptimal detectors can be enhanced by adding independent noise to their inputs via the stochastic resonance (SR) effect. In this paper, the effects of SR are studied for binary composite hypothesis-testing ... -
Stochastic signaling in the presence of channel state information uncertainty
(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 ... -
Time delay estimation in cognitive radio systems
(IEEE, 2009-12)In cognitive radio systems, secondary users can utilize multiple dispersed bands that are not used by primary users. In this paper, time delay estimation of signals that occupy multiple dispersed bands is studied. First, ...
