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.
紫外光通信具有非常好的非視距傳輸和保密性能.傳統的紫外光通信繫統呎吋過大,難以實際應用.基于紫外線髮光二級管(UV-LED)設計瞭一箇紫外光通信繫統,研究瞭光路設計、時鐘恢複、信道編碼等方麵的內容,併重點設計瞭雙工傳輸協議,用較小的資源實現瞭4.8 Kb/s信息的傳輸.該繫統可以用于近距離語音和數據的雙嚮保密傳輸.

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 re-source. This system can be used for duplex secrecy communication of voice and data in close range.
