Design of a VLC-based beaconing infrastructure for indoor localization applications

In this paper the design of an LED-based beaconing infrastructure is introduced, which can be utilized in indoor localization systems. The LED beacons, which may be part of the existing lighting infrastructure, are blinking with high frequency invisible for human eyes, while the detectors are regular cameras. Since the sampling frequency of the cameras is much lower than the blinking frequency, the detection is based on a coding system, which tolerates the undersampling of the signal. The performance of the proposed system is analyzed and a possible application is introduced.
