Visible light communication based motion detection

Indoor Localization Based on Visible Light Communication

Visible Light Communication

The visible light communication (VLC) refers to the communication technology which utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate photodiode as a signal receiving component. The visible light communication technology has a short history compared with other communication technology, for example, public old telephone service, Ether...

Spatial Interference Detection for Mobile Visible Light Communication

With the explosion of the Internet of Things (IoT), the number of devices to identify grew up exponentially in recent years and solutions such as visual markers or radio technologies are starting to show their limits. Visible light markers have been proposed to overcome these limitations. However, visible light communication (VLC) is very sensitive to interferences. As such, if two light marker...

Software Defined Visible Light Communication

Software Defined Radio (SDR) has proven to be a practical and effective tool in RF communications, allowing flexible and rapid exploration of dynamic RF signal processing techniques while accelerating advancement of configurable RF antennas and front-end hardware. SDR concepts can be adapted to other physical media; we investigate a Software Defined Visible Light Communications (SDVLC) solution...

High - speed visible light communication system based on SiPM

Silicon Photomultiplier (SiPM) is a photodetector with very high sensitivity, fast response and good performance in oversaturation conditions. When SiPM faces incident optical radiation (sometimes imperceptible for other photodetectors) is able to detect very small variations of light. In this work, we present a SiPM-based optical receiver ables to discriminate small light signals from backgrou...
