Distributed 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...
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 کاملConstellation Design for Multi-color Visible Light Communications
In this paper, we propose a novel high dimensional constellation design scheme for visible light communication (VLC) systems employing red/green/blue light emitting diodes (RGB LEDs). It is in fact a generalized color shift keying (CSK) scheme which does not suffer efficiency loss due to a constrained sum intensity for all constellation symbols. Crucial lighting requirements are included as opt...
متن کاملVisible Light Communications
Visible light communication (VLC) is an optical wireless communication technology that uses low-power light-emitting diodes (LEDs) to not only provide light, but also broadcast data [1–3]. LEDs are extremely energy-efficient and are expected to become widespread in general lighting applications. Because LEDs are solid-state lighting devices, they can be modulated at high speed compared to other...
متن کاملBlind Fractional Interference Alignment
Fractional Interference Alignment (FIA) is a transmission scheme which achieves any value between [0,1] for the Symbols transmitted per Antenna per Channel use (SpAC). FIA was designed in [1] specifically for Finite Alphabet (FA) signals, under the constraint that the Minimum Distance (MD) detector is used at all the receivers. Similar to classical interference alignment, the FIA precoder also ...
