Deep cooperation for optical communication and positioning in mobile scenarios

Joint communication and positioning are increasingly demanded in mobile scenarios. But related works concerning integrated visible light communication and positioning systems mainly focus on the unilateral performance optimization, which restricts the efficiency and integral performance of the systems. This Letter exploits the cooperative enhancement mechanism between communication and positioning and proposes a cycling system framework to jointly implement the communication and positioning. An iterative method is designed to perform the mutual enhancement of positioning accuracy and received signal intensity by the system. Experimental results show that a positioning accuracy of 3.62 cm and a signal intensity improvement of 3-7 dB can be simultaneously achieved.
