Abstract
In this paper, we propose an indoor visible light positioning system which is based on time difference of arrival (TDOA). Compared to current TDOA which uses square wave for pilot signal, our system uses sinusoidal wave for pilot signal. Our proposed system is simulated in the room measuring 5×5×3m3. In the simulations, we consider the effects shot noise, thermal noise and noise from reflected light. The simulation results show that the estimation accuracy is 68.2cm on average with using 10ns sampling and with consideration of rising time of LED and PD.
