Passive visible light positioning systems [PDF]

open access: yesProceedings of the Workshop on Light Up the IoT, 2020
Localization is one of the key applications of visible light communication (VLC) using which sub-centimeter level positioning accuracy is possible. Many visible light-based positioning (VLP) systems have been designed by industry and the research community. Their commercial viability is hampered by the requirement of significant changes in the deployed

A Comprehensive Study on Light Signals of Opportunity for Subdecimetre Unmodulated Visible Light Positioning [PDF]

open access: yesSensors, 2020
Currently, visible light positioning (VLP) enabling an illumination infrastructure requires a costly retrofit. Intensity modulation systems not only necessitate changes to the internal LED driving module, but decrease the LEDs’ radiant flux as well. This

Effects of cooperation on visible light positioning [PDF]

open access: yes2017 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

Current Trends on Visible Light Positioning Techniques [PDF]

open access: yes2019 2nd West Asian Colloquium on Optical Wireless Communications (WACOWC), 2019
This paper presents a survey on visible light positioning techniques. The paper briefly reviews conventional positioning methods based on Rx signal strength (RSS), time difference of arrival (TDOA) and angle of arrival (AOA). Then it focus on the current research trends, relying on the machine learning techniques, sensor fusion and communication ...

Indoor Real-Time 3-D Visible Light Positioning System Using Fingerprinting and Extreme Learning Machine

open access: yesIEEE Access, 2020
Photodiode-based (PD-based) visible light positioning (VLP) has become a research focus of indoor positioning technology, while the existing VLP models rarely consider the anti-interference and positioning time of that.

Polarization-Based Visible Light Positioning

open access: yesIEEE Transactions on Mobile Computing, 2019
Visible Light Positioning (VLP) provides a promising means to achieve indoor localization with sub-meter accuracy. We observe that the Visible Light Communication (VLC) methods in existing VLP systems rely on intensity-based modulation, and thus they require a high pulse rate to prevent flickering.
