摘要：

Indoor visible light positioning (VLP) system has drawn more and more attention in recent years. In this paper, we propose a new positioning scheme, which utilizes a close-range signal selection method and weighted mean algorithm based on received signal strength ratio (RSSR). The new scheme can effectively improve the positioning accuracy at the corners and edges of the room, that is, it can obviously reduce the impact of reflections on indoor VLP system. Simulation results show that compared with the RSSR method, the proposed scheme has improved the positioning error by at least about 38 cm, and can achieve an average positioning error of 0.0806 m in the case of 25 LEDs. Then, the positioning errors are further analyzed for several different layouts of LEDs.
