Abstract

In this work, an experimental time division duplex system is presented to prevent interference in visible light communication. The 40-LED array and a single LED were used for downlink and uplink respectively. The interference of signal reflection on mirrors was discussed and removed using time division duplex. At the distance of 2 m, the data rate achieved is above 1Mbps with bit error rate below 2×10^-5 in each of the direction.
