Novel Integrated power line and visible light communication system with bit division multiplexing

Visible light communication (VLC), as an appealing alternative to the classical radio frequency communication technologies, has a bright application prospect for future wireless communications. In this paper, we propose an integrated power line communication (PLC) and VLC system with bit division multiplexing (BDM). By the integration of VLC with PLC, the lamp can work as light source as well as access point, and the architecture of VLC network could be significantly simplified. Meanwhile, the BDM scheme could simultaneously support multi-service, e.g., data transmission and navigation services as global and local services, respectively, in a natural single frequency network (SFN) structure with low complexity, high spectral efficiency, and easy switching protocol as well. Simulation results demonstrate that this proposed scheme can accommodate different requirements of quality of service (QoS) and outperform conventional multi-service schemes with time-frequency channel resource allocation approaches.
