In this paper, we propose a joint design of polar codes and physical-layer network coding in visible light communication (VLC) system. Polar codes could correct bit errors and enhance the reliability, and physical-layer network coding could reduce time slots required in the bidirectional communication and improve the transmission efficiency. The simulation results show that our scheme approaches the bit error rate (BER) of the conventional scheme, and further increases the throughput by 100% and reduces the equipment cost by 50%. The proposed design enhances the performance of VLC system noticeably and is more suitable for VLC system with the low-latency demand.
