Modulation Schemes for Visible Light Communications
2019 International Conference on Advanced Communication Technologies and Networking (CommNet), 2019Visible light communication (VLC) is one of the most recent technological breakthroughs in wireless communications and it is expected to contribute significantly on future generations of mobile communications. The fundamental feature of VLC is the use of visible light spectrum to transmit data along with the traditional use for illumination.

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 ...

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.

36th European Conference and Exhibition on Optical Communication, 2010
Visible light communication is a novel way of indoor communication. In this scenario, we present the novel idea of location-based services such as indoor navigation systems, where users can tell where they are by detecting a signal from LED lights.

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

About Lighting Level of the Visible Light Communication
2018 IEEE 7th Global Conference on Consumer Electronics (GCCE), 2018In visible light communication in which information is superimposed on light, its communication range is visible. On the other hand, when the modulation that brightness is changed according to information is used, it is not good for the human eye because human feels flicker for the changed brightness.
