Comparative theoretical analysis of distance estimation in visible light positioning systems
(Institute of Electrical and Electronics Engineers Inc., 2016)In this paper, theoretical limits and estimators are studied for synchronous and asynchronous visible light positioning (VLP) systems. Specifically, the Cramér-Rao lower bounds (CRLBs) and maximum likelihood estimators are ... -
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 ... -
Fundamental limits on localization in single input multiple output visible light systems
(Bilkent University, 2017-09)Visible light systems have recently been considered as an e ective and promising solution for indoor positioning. In this thesis, a theoretical accuracy analysis is conducted for position estimation in visible light ... -
Improved lower bounds for ranging in synchronous visible light positioning systems
(Institute of Electrical and Electronics Engineers Inc., 2016)In this study, the Ziv-Zakai bound (ZZB) is derived for synchronous visible light positioning (VLP) systems. The proposed ZZB extracts ranging information from the prior information, the time delay parameter, and the channel ...
