An illumination perspective on visible light communications
IEEE Communications Magazine, 2014Visible light communications are the offspring of well studied infrared wireless systems and can form a promising enhancement of future illumination infrastructures with communication functionalities. However, supporting data rates of hundreds of megabits per second cannot come for free with respect to lighting system costs.

Cooperative Visible Light Communications
2016In this chapter, we explore the concept of cooperative transmissions in the context of visible light communications (VLC). An indoor office space is considered with two light sources; the one at the ceiling is connected to the backbone network and provides ambient light to the environment while the other one is mounted on the desk and used for task ...

2013 Texas Instruments India Educators' Conference, 2013
Light Emitting Diodes are set to penetrate many areas of everyday life. An interesting property of these devices in addition to their lightening capabilities, is that they can also be utilised for data transmissions as well. LED's require low power for their operation and have very high switching speeds.

Vehicular Visible Light Communications: A Survey
IEEE Communications Surveys & Tutorials, 2021Visible Light Communications (VLC) is becoming a mature communication technology, particularly for indoor usage. The application in outdoor environments is especially interesting in the scope of Vehicular VLC (V-VLC), however, there are some critical challenges remaining. In general, VLC is a good complement to Radio Frequency (RF)-based communication.

Light-emitting diodes for visible light communication
2015 International Wireless Communications and Mobile Computing Conference (IWCMC), 2015Conventional LEDs always pursue the high brightness for solid-state lighting, however, they always exhibit very low frequency bandwidth of tens MHz. As an application, visible light communication (VLC) is not only for illumination but also for data transmission communication, which is a kind of optical wireless communication that uses the visible white

A SNR analysis of the visible light channel environment for visible light communication
2012 18th Asia-Pacific Conference on Communications (APCC), 2012In this paper, we provide Signal-to-Noise Ratio (SNR) analysis of visible light channel environment reflecting practical conditions for the usage of Visible Light Communication (VLC) in Intelligent Transportation System (ITS). Considering practical LED lights (Headlamp and Streetlamp), we perform 3D computer simulations in two ITS scenario.

Optical OFDM for visible light communications
2017 13th International Wireless Communications and Mobile Computing Conference (IWCMC), 2017Visible light communication (VLC) has become a promising complement to its radio-frequency (RF) counterpart. In VLC systems, orthogonal frequency division multiplexing (OFDM) has drawn much attention due to its high data rate, simple equalization and robustness to the inter-symbol interference (ISI).
