短距离紫外光通信系统设计研究

Design of short-range ultraviolet communication system

紫外光通信是无线通信与光通信相结合的一种较新的通信技术,以光为载体,并不通过任何有形实体介质进行信息传输,在现有几种解决"最后一公里"问题的技术中有很大优势。基于日盲区段的紫外光通信与基于可见光波段的无线光通信技术,是近年来的研究热点,并在无线光通信系统中引入并得到迅速发展,具有逼近香农限优良性能的"好"码-LDPC信道编码。

UV communication is wireless communication to communicate with light combines a relatively new communication technologies to light as the carrier, not by any entity tangible medium of information transmission in several existing solve the “last mile”problem the technology has great advantages. UV-based communications segment blind date with a visible light-based optical wireless communication technology, the research focus in recent years, and the introduction and rapid development in wireless optical communication system with excellent performance close to the Shannon limit“good”code-LDPC channel coding.
