Estimation theoretic secure communication via encoder randomization
(IEEE, 2019-12-01)
Estimation theoretic secure transmission of a scalar random parameter is investigated in the presence of an eavesdropper. The aim is to minimize the estimation error at the receiver under a secrecy constraint at the ...
Hybrid TDOA/RSS based localization for visible light systems
(Elsevier, 2018)
In a visible light positioning (VLP) system, a receiver can estimate its location based on signals transmitted by light emitting diodes (LEDs). In this manuscript, we investigate a quasi-synchronous VLP system, in which ...
On the number of bins in equilibria for signaling games
(IEEE, 2019-07)
We investigate the equilibrium behavior for the decentralized quadratic cheap talk problem in which an encoder and a decoder, viewed as two decision makers, have misaligned objective functions. In prior work, we have shown ...
Optimal joint modulation classification and symbol decoding
(IEEE, 2019-05)
In this paper, modulation classification and symbol decoding problems are jointly considered and optimal strategies are proposed under various settings. In the considered framework, there exist a number of candidate ...
Estimation theoretic optimal encoding design for secure transmission of multiple parameters
(IEEE, 2019-08-15)
In this paper, optimal deterministic encoding of a vector parameter is investigated in the presence of an eavesdropper. The objective is to minimize the expectation of the conditional Cramér-Rao bound at the intended ...
Jamming strategies in wireless source localization systems
(IEEE, 2019-08)
We consider optimal jamming strategies in wireless source localization systems, where anchor nodes estimate positions of target nodes in the presence of jammers that emit zero-mean Gaussian noise. The Cramér-Rao lower bound ...
Optimal and robust power allocation for visible light positioning systems under illumination constraints
(IEEE, 2019-01)
The problem of optimal power allocation among light emitting diode (LED) transmitters in a visible light positioning system is considered for the purpose of improving localization performance of visible light communication ...
Cooperative localization in hybrid infrared/visible light networks: theoretical limits and distributed algorithms
(Institute of Electrical and Electronics Engineers, 2018-03)
Light emitting diode (LED) based visible light positioning (VLP) networks can provide accurate location information in environments where the global positioning system (GPS) suffers from severe signal degradation and/or ...
Accuracy limits of distance estimation in visible light systems with RGB LEDs
(IEEE, 2019-09)
The distance estimation problem is investigated for visible light positioning (VLP) systems with red-green-blue (RGB) light emitting diodes (LEDs). The accuracy limits on distance estimation are calculated in terms of the ...
Binary signaling under subjective priors and costs as a game
(Institute of Electrical and Electronics Engineers Inc., 2019)
Many decentralized and networked control problems involve decision makers which have either misaligned criteria or subjective priors. In the context of such a setup, in this paper we consider binary signaling problems in ...
