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 کاملDimming-discrete-multi-tone (DMT) for simultaneous color control and high speed visible light communication.
Visible light communication (VLC) using LEDs has attracted significant attention recently for the future secure, license-free and electromagnetic-interference (EMI)-free optical wireless communication. Dimming technique in LED lamp is advantageous for energy efficiency. Color control can be performed in the red-green-blue (RGB) LEDs by using dimming technique. It is highly desirable to employ d...
متن کاملNetwork-Centric and User-Centric Multi-User Scheduling in Visible Light Communication aided Networks
Visible Light Communication (VLC) combined with advanced illumination has been expected to become an integral part of next generation heterogeneous networks at the time of writing, by inspiring further research interests. From both the Network-Centric (NC) and the User-Centric (UC) perspectives, various VLC cell formations, ranging from fixed-shape regular cells with different Frequency Reuse (...
متن کاملDimming Consideration for OFDM-Based Visible Light Communications
In the field of indoor wireless networks, visible light communications would be contributing a vital role in the future. This paper investigates the performances of data transmissions using visible light based on unipolar orthogonal frequency division multiplexing (OFDM) and discusses possible approach for light dimming. Asymmetrically clipped optical OFDM (ACO-OFDM) is considered as a unipolar...
متن کاملDistributed user-centric scheduling for visible light communication networks.
Visible light communication (VLC) networks, consisting of multiple light-emitting diodes (LEDs) acting as optical access points (APs), can provide low-cost high-rate data transmission to multiple users simultaneously in indoor environments. However, the performance of VLC networks is severely limited by the interference between different users. In this paper, we establish a distributed user-cen...
