This paper presents the use of a selective device based on a-SiC: H/a-Si: H for the
photodetection of visible signals emitted by red, green and blue emitters in a Visible Light …

This paper studies a novel way to estimate the position of an object in an indoor
environment, using the Channel State Information (CSI) that a Visible Light Communication …

Global positioning system uses satellite signals to infer position. In buildings, however, these
signals are attenuated and scattered by walls and other objects, making it impossible to …

In this paper a real-time Indoor Positioning System (IPS) based on Visible Light
Communication (VLC) is proposed, deployed and studied. It is composed of nine LED …

We explore the use of smartphones to decode data transmitted from LEDs to smartphone
cameras in visible light communication (VLC) applied to indoor positioning applications. The …

In this work, the use of courtesy lamps for communicating with visible light has been
proposed for low cost indoor positioning. Modulated light emitting diode (LED) lights have …

Indoor positioning systems based on visible light communication (VLC) using white light-
emitting diodes (WLEDs) have been widely studied in the literature. In this paper, we present …

In this paper an integrated wavelength optical filter and photodetector working as a DEMUX
device is used to detect modulated optical signals of visible wavelengths for Visible Light …

An novel concept for integrating visible light produced by LEDs with indoor positioning using
multiple optical receivers is presented in this study. We propose an algorithm using the …

Indoor positioning system (IPS) coupling with photo-detectors at the receiving end has
gained much attention from the consumers. The accuracy level using the global positioning …
