A Survey of Positioning Systems Using Visible LED Lights [PDF]
IEEE Communications Surveys and Tutorials, 2018 As Global Positioning System (GPS) cannot provide satisfying performance in indoor environments, indoor positioning technology, which utilizes indoor wireless signals instead of GPS signals, has grown rapidly in recent years. Meanwhile, visible light communication (VLC) using light devices such as light emitting diodes (LEDs) has been deemed to be a ...

Effects of cooperation on visible light positioning [PDF]
2017 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2017 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 Cramer-Rao lower bound expression. The obtained expression is generic for any three-dimensional configuration and covers all possible cooperation scenarios
