Direct and two-step positioning in visible light systems
(IEEE, 2018)Visible light positioning (VLP) systems based on light emitting diodes can facilitate high accuracy localization services for indoor scenarios. In this paper, direct and two-step positioning approaches are investigated for ... -
Direct positioning in synchronous and asynchronous visible light systems
(IEEE, 2018)In this paper, direct positioning approaches are investigated for both synchronous and asynchronous visible light systems. First, the maximum likelihood estimator (MLE) and the Cramér-Rao lower bound (CRLB) are derived for ... -
Effects of cooperation on visible light positioning
(IEEE, 2018)In this paper, cooperative localization is proposed for visible light systems. The effects of cooperation on the localization accuracy of visible light positioning systems are illustrated based on a Cramér-Rao lower bound ... -
Image processing methods for computer-aided interpretation of microscopic images
(Bilkent University, 2012)Image processing algorithms for automated analysis of microscopic images have become increasingly popular in the last decade with the remarkable growth in computational power. The advent of high-throughput scanning devices ... -
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 ... -
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 ... -
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 ... -
Visible light positioning systems: fundamental limits, algorithms and resource allocation approaches
(Bilkent University, 2018-08)Visible light communication (VLC) is an emerging paradigm that enables multiple functionalities to be accomplished concurrently, including illumination, highspeed data communications, and localization. Based on the VLC ...
