Visible Light Communication for Wireless Data Transmission
Visible Light Communication (VLC) technology, one of the advanced optical wireless communication technologies, in which light in the visible region (375nm-780nm) is used as a medium for data transmission is more secure and achieves high data rates as compared to conventional wireless technologies like Wi-Fi, Bluetooth, Wi-max etc., which use radio waves for communication. While using wireless i...
متن کاملDigital Signal Processing for Light Emitting Diode Based Visible Light Communication
The realization of enhanced efficiency light emitting diodes (LED) and the trend to lower costs of LED lighting systems will facilitate their wider deployment in many applications. LED lighting system with the value-added functionality of optical wireless communication enables the deployment of a communication system with very little extra cost. Visible light communication (VLC) provides the me...
متن کاملDynamic Channel Selection Scheme for IEEE 802.15.7 Visible Light Communication
In visible light communication, due to the limitation and heterogeneous effect of color channel on different environment, the link quality will effect. In this article, new approach for multi-channel MAC for visible light communication, named dynamic channel selection cognitive MAC. Numerical results show that, with the proposed system, we can reduce the blocking probability and improve the sys...
متن کاملVisible Light Communication Systems for Optical Video Transmission
This article describes an optical wireless system based on visible light communication (VLC), which allows a video broadcasting to reach a bit rate of 1 Mbps, although this system can also be used for low-speed sensor interconnections. The main advantages of this technology are the robustness against EM interference, safety for human eye, and security against undesired network access. In this a...
متن کاملReview of Ofdm Modulation Scheme for Indoor Visible Light Communication System
Visible light communication (VLC) system for small range transmission uses visible spectrum which provides illumination simultaneously. Designing cost of light emitting diodes was reduced in order to make this communication possible. A modulation technique which can effectively employ the bandwidth is orthogonal frequency division multiplexing (OFDM) technique. This technique has a unique form ...
