Indoor Visible Light Positioning with Angle Diversity Transmitter

2015 IEEE 82nd Vehicular Technology Conference (VTC2015-Fall), 2015
A new concept for indoor positioning using visible light communication (VLC) is presented in this paper. The feasibility of uplink localization is verified so that the proposed system can work in conjunction with downlink positioning systems to improve overall localization accuracy. We propose to use an angle diversity transmitter (ADT) associated with

Visible Light Positioning Using an Aperture and a Quadrant Photodiode

2017 IEEE Globecom Workshops (GC Wkshps), 2017
This paper describes a new form of angle of arrival (AOA) detector which can be applied in an indoor visible light positioning system using LED luminaires. In this new detector, a quadrant photodiode (PD) is placed below a transparent aperture in an opaque screen. Light passing through the aperture creates an illuminated area on the quadrant PD.

Optimizing Visible Light Illumination and Positioning

2020
The fast electrical switching of electrical signals in an LED illumination bulb allows it to be used for both Visible Light Communication (VLC) and Visible Light Positioning (VLP). An indoor simple, fast, geometric positioning system called the Binary Search Algorithm which uses RSSI trilateration is introduced. It is robust against noise. When dealing

Turn on the lights: leveraging visible light for communications and positioning

SPIE Proceedings, 2015
The need for ubiquitous broadband connectivity is continually growing, however, radio spectrum is increasingly scarce and limited by interference. In addition, the energy efficiency of many radio transmitters is low and most input energy is converted to heat.

Visible light positioning using a camera

2020
Esta dissertação tem como objetivo o desenvolvimento de um sistema de posicionamento em espaços interiores através de uma câmara. O sistema proposto utiliza a câmara como o único sensor, obtendo a sua posição numa sala com luminárias LED devidamente moduladas.
