Current Trends on Visible Light Positioning Techniques [PDF]
2019 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 ...

Angle diversity to increase coverage and position accuracy in 3D visible light positioning [PDF]
, 2019 The most common approach to light-based indoor positioning relies on multilateration of received signals to the mobile device. Any deficiencies in the fidelity of these light signals can significantly distort position estimates. In this paper, we propose

An analysis of the impact of LED tilt on visible light positioning accuracy [PDF]
, 2019 Whereas the impact of photodiode noise and reflections is heavily studied in Visible Light Positioning (VLP), an often underestimated deterioration of VLP accuracy is caused by tilt of the Light Emitting Diodes (LEDs).
