英文摘要： Visible light communication (VLC) is becoming a booming research topic because its advantage of energy saving and broad bandwidth compared to wirless communication. With the increasing demand of high precision indoor positioning and location based service, we propose in this project to research 3D indoor positing system and network based on visible light communication. The critical issue concerning the indoor positioning system based on VLC is to improve its positioning accuracy and reliability, and the theoretical and experimental research will be carried on the design of LED layout and Lens antenna,modulation format and modulation depth,3D positioning algorithm and the fusion with sensors. On the networking of visible light positioning system, asynchronous networking mechanism and principle of the different users among inter-cell and different inter-cell will be studied, and the method to fulfill a uplink and downlink bi-direction communication networking will be proposed. In this project, fundamental research including theory and experiment will be focused to realize the high accuracy indoor positioning based on visible light communication. A proof indoor positioning system and network will be built to verify the proposed theoretical model, working principle, digital signal processing algorithm and methods. The research results in this project will have great significance and potential application prospects in the field of indoor positioning and navigation.
