Visible light positioning: a roadmap for international standardization
IEEE Communications Magazine, 2013The widespread introduction of white LEDs for illumination provides a unique opportunity to create an indoor positioning system that is flexible, accurate, and ubiquitous. Signals transmitted by the LEDs are used to determine the position of a person or object within a room.

Visible light positioning: Automotive use case
2010 IEEE Vehicular Networking Conference, 2010The use of positioning sensors on automobiles is becoming increasingly common with the desire to facilitate utility and traffic safety by giving the driver information on the automobiles position relative to the surroundings. In this paper we introduce a positioning technique based upon automobile LED lighting — either taillights or headlights — that ...

Indoor Position Tracking Using Visible Light
2015 IEEE 82nd Vehicular Technology Conference (VTC2015-Fall), 2015The demand for a highly accurate indoor positioning system is rapidly increasing. In the last few years, several positioning systems based on visible light communications that achieve good positioning accuracy have been proposed. However, these systems are based on assumptions such as complete knowledge of the height of the receiver, exact alignment of

Indoor positioning with OFDM Visible Light Communications
2016 13th IEEE Annual Consumer Communications & Networking Conference (CCNC), 2016Visible Light Communication (VLC) technology using light emitting diodes (LEDs) has been gaining increasing attention in recent years as it is appealing for a wide range of applications such as indoor positioning. Orthogonal frequency division multiplexing (OFDM) has been applied to indoor wireless optical communications in order to mitigate the effect

Visible Light Positioning Based on LED Traffic Light and Photodiode
2011 IEEE Vehicular Technology Conference (VTC Fall), 2011This paper presents visible light positioning (VLP) techniques based on a traffic light and photodiodes. The position of a vehicle can be determined using both the traffic light position information obtained through a visible light communication (VLC) link and the time difference of arrival (TDOA) of the traffic light signal to two photodiodes mounted ...

Optical OFDM for Visible Light Communications and Visible Light Positioning
2019This thesis addresses key aspects of practical visible light communication (VLC) systems. The research can be divided into three main topics. First, the limited data rate of current VLC systems is addressed in two ways. A performance analysis of the most important VLC modulation formats has been described and a new receiver for one of these schemes has

Indoor Visible Light Positioning with Angle Diversity Transmitter
2015 IEEE 82nd Vehicular Technology Conference (VTC2015-Fall), 2015A 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), 2017This 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
2020The 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
