摘要
针对室内可见光通信系统中全光通信链路不易实现的问题,设计并搭建了一种基于离焦型猫眼逆向调制方案的室内可见光单光源全双工通信系统。该系统上下行链路相互独立,克服了传统单光源双工通信系统需要收发两端配合通信的不利因素,无须增加额外的光源就可以实现全光链路的双工通信。实验结果表明:该系统可在3.0 m的通信距离条件下实现下行5.0 Mbit/s、上行2.0 kbit/s的数据传输。
Abstract
An indoor visible light single-source full-duplex communication system is designed and constructed based on inverse modulation of defocused cat eye aiming at hard realization problem of all-optical communication link in indoor visible light communication system. The uplink and downlink of system are independent on each other. It overcomes the disadvantage that traditional single-source duplex communication system needs coordination of transmitter and receiver at the two ends with communication, and can realize the duplex communication of all-optical link without adding additional light source. The experimental results show that the system can realize the downlink 5.0 Mbit/s and uplink 2.0 kbit/s data transmission under the condition of 3.0 m communication distance.
