Optimal jammer placement in wireless localization networks
(IEEE, 2015-06-07)
The optimal jammer placement problem is proposed for a wireless localization network, where the aim is to degrade the accuracy of locating target nodes as much as possible. In particular, the optimal location of a jammer ...
Optimum power randomization for the minimization of outage probability
(IEEE, 2013)
The optimum power randomization problem is studied to minimize outage probability in flat block-fading Gaussian channels under an average transmit power constraint and in the presence of channel distribution information ...
On the performance of linear least-squares estimation in wireless positioning systems
(IEEE, 2008-05)
A common technique for wireless positioning is to estimate time-of-arrivals (TOAs) of signals traveling between a target node and a number of reference nodes, and then to determine the position of the target node based on ...
Enhancements to linear least squares localization through reference selection and ML estimation
(IEEE, 2008-03-04)
Linear least squares (LLS) estimation is a low complexity but sub-optimum method for estimating the location of a mobile terminal (MT) from some distance measurements. It requires selecting one of the fixed terminals (FTs) ...
Noise enhanced detection in restricted Neyman-Pearson framework
(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 ...
Theoretical limits and a practical estimator for joint estimation of respiration and heartbeat rates using UWB impulse radio

In this study, the optimal channel switching problem is investigated for average capacity maximization in the presence of channel switching delays. First, the optimal strategy is obtained and the corresponding average ...
Maximization of correct decision probability via channel switching over Rayleigh fading channels
(IEEE, 2016)
In this study, optimal channel switching (time sharing) strategies are investigated under average power and cost constraints in order to maximize the average number of correctly received symbols between a transmitter and ...
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 ...
Stochastic signal design on the downlink of a multiuser communications system
(IEEE, 2012-06)
Stochastic signal design is studied for the downlink of a multiuser communications system. First, a formulation is proposed for the joint design of optimal stochastic signals. Then, an approximate formulation, which can ...
