Direct and Two-Step Positioning in Visible Light Systems [PDF]

IEEE Transactions on Communications, 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 both synchronous and asynchronous VLP systems.

DarkVLP: “Lights-Off” Visible-Light Positioning

IEEE Internet of Things Journal, 2022
Visible Light Positioning (VLP) has been considered as a promising indoor positioning technology due to its high precision and low cost. However, current visible light positioning techniques are greatly limited by the assumption that lights have to be turned on to emit shining light beams, which is not applicable to scenarios that do not need the ...

Signature Codes in Visible Light Positioning

IEEE Wireless Communications, 2021
With the explosive development of the Internet of Things (IoT), massive equipments are involved in the indoor environment with the demand of precise localization to provide intelligent interconnection. The visible light positioning (VLP) system, with the light emitting diode (LED) and the photo-diode (PD) or image sensor as the transceiver, has ...

Passive Positioning using Visible Light Systems

Optical Fiber Communication Conference (OFC) 2021, 2021
Passive indoor visible light localization detects changes in illumination patterns in a room to infer the position of a user. We present analytical bounds on positioning error of an object in an indoor scenario and use deep learning to estimate positioning in realistic scenarios.
