Abstract

A novel design of three dimensional optical receiver for visible light communication (VLC) indoor positioning system has been proposed in this paper. We model the optical wireless channel and utilize modified triangulation method to obtain more robust receiver position by using at least two LEDs and one receiver consisting of nine photodetectors (PDs). The main characteristics are as follows: (1) our design of multi-PDs receiver is fully expanded into three dimensions compared with the pyramid structure (PR); (2) based on Multiple-Photodiode-based Indoor Positioning algorithm [1], we improve the indoor positioning algorithm by redefining the optimization problem of obtaining the direction from receiver to LED and using weighted triangulation method to locate receiver position; (3) the improved algorithm is implemented and the simulation results are shown under our three dimensional multi-PDs structure receiver.
