VLC system transmits data by controlling LED and receives data through photo diode, which is considered as one of strong candidates of next generation wireless communication systems. Especially, VLC shows a better performance than the existing indoor positioning technology using WPAN as it can measure in the unit of cm to mm. In this paper, we proposed an algorithm for estimating the position of mobile station by comparing the received light intensity at the receiver with the pre-calculated light intensity at a given position. The simulation results verified that the proposed estimation algorithm of an indoor VLC system can be providing good position accuracy.
