摘要
紫外光通信具有非常好的非视距传输和保密性能。传统的紫外光通信系统尺寸过大,难以实际应用。基于紫外线发光二级管(UV-LED)设计了一个紫外光通信系统,研究了光路设计、时钟恢复、信道编码等方面的内容,并重点设计了双工传输协议,用较小的资源实现了4.8 Kb/s信息的传输。该系统可以用于近距离语音和数据的双向保密传输。
Ultraviolet（UV）light communication system has better non-line-of-sight transmission and secrecy performance.For the traditional UV-light communication system has large size,and is hard to apply in practice,an UV-light communication system was designed based on UV-LED. The contents of optical path design,clock recovery and channel coding are studied. The duplex communication protocol was designed emphatically. The information transmission of 4.8 Kb/s was realized with less resource. This system can be used for duplex secrecy communication of voice and data in close range.
