Abstract

The paper experimentally demonstrates the indoor positioning in Visible Light Communication（VLC） system based on white light. The paper proposes the model of indoor positioning in VLC system and its hardware design. The paper also introduces a positioning algorithm based on the Fast Fourier Transform（FFT）. Meanwhile

we also have done the relevant experiments and get the data which has the maximum error of 14.866 cm. Experimental results show that the system can solve the indoor positioning problem.
