Abstract :
The angle of arrival (AOA) algorithm, based on indoor visible light communication (VLC) system is analyzed in this paper. First the indoor VLC positioning system is introduced in detail. Then the Cramer-Rao bound (CRB) as the theoretical accuracy of AOA algorithm is derived. The performance of the positioning system is determined by incidence angle of light, the height of the room and the SNR of the system. It is concluded that the positioning accuracy is under 8 cm when the SNR is 80 dB by simulation.
