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 ...
Noise benefits in joint detection and estimation problems
(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. ...
Optimal parameter encoding based on worst case fisher information under a secrecy constraint
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this letter, optimal deterministic encoding of a uniformly distributed scalar parameter is performed in the presence of an eavesdropper. The objective is to maximize the worst case Fisher information of the parameter ...
Cost minimization of measurement devices under estimation accuracy constraints in the presence of Gaussian noise
(Elsevier, 2012)
Novel convex measurement cost minimization problems are proposed based on various estimation
accuracy constraints for a linear system subject to additive Gaussian noise. Closed form solutions are
obtained in the case of ...
Position estimation via ultra-wide-band signals
(IEEE, 2009-02-27)
The high time resolution of ultra-wide-band (UWB) signals facilitates very precise position estimation in many scenarios, which makes a variety applications possible. This paper reviews the problem of position estimation ...
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 ...
Average fisher information optimization for quantized measurements using additive independent noise
(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 ...
Theoretical limits for estimation of vital signal parameters using impulse radio UWB
(IEEE, 2007)
In this paper, Cramer-Rao lower bounds (CRLBs) for estimation of vital signal parameters, such as respiration and heart-beat rates, using ultra-wideband (UWB) pulses are derived. In addition, a simple closed-form CRLB ...
Optimal stochastic design for multi-parameter estimation problems
(IEEE, 2014- 05)
In this study, we consider performance improvement of an array of fixed estimators by using stochastic design techniques. The optimal design is investigated both in the absence and presence of an average power constraint. ...
ECRB-based optimal parameter encoding under secrecy constraints
(Institute of Electrical and Electronics Engineers, 2018)
In this paper, optimal deterministic encoding of a scalar parameter is investigated in the presence of an eavesdropper. The aim is to minimize the expectation of the conditional Cramér-Rao bound at the intended receiver ...
