It was assumed that the adjacent LEDs transmit information in different time slots to eliminate mutual interference. The Lambertian-based positioning method was evaluated via both simulations and experiments. Based on experimental measurements, the indoor positioning accuracy can reach the order of centimeters. In particular, the improved algorithm shows lower computational complexity and good robustness to the peak-to-peak voltage difference of different LEDs.
