This paper studies an indoor communication system that integrates visible light communication (VLC) and power line communication (PLC) technologies. We exploit the application of the same orthogonal multicarrier modulation format for both PLC and LC link and present the framework for the capacity analysis of the hybrid VLC-PLC (HVP) system. In addition, several computationally efficient subcarrier allocation schemes are proposed to maximize the system capacity. The results demonstrate that the proposed subcarrier allocation in the HVP system can provide an improvement in the system capacity over random subcarrier allocation.
