摘要

本文提出了一种防止可见光通信干扰的实验时分双工系统。下行链路采用40个LED阵列，上行链路采用单个LED。讨论了反射信号对反射镜的干扰，并采用时分双工技术消除了反射镜的干扰。在2米的距离上，实现的数据速率在1Mbps以上，每个方向的误码率在2×10-5以下。

Time division duplex for preventing reflection interference in visible light communication

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.
