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 ...
Positioning algorithms for cooperative networks in the presence of an unknown turn-around time
This paper addresses the problem of single node positioning in cooperative network using hybrid two-way time-of-arrival and time-difference-of-arrival where, the turn-around time at the target node is unknown. Considering ...
Hybrid TW-TOA/TDOA positioning algorithms for cooperative wireless networks
The problem of positioning an unknown target is studied for a cooperative wireless sensor network using hybrid two-way time-of-arrival and time-difference-of-arrival measurements. A maximum likelihood estimator (MLE) can ...
