室内可见光局域网的研究

在室内无线光局域网中,可见光通信越来越引起了人们的关注。可见光通信具有发射功率高、无需申请频谱、无电磁干扰、节约能源等优点,因此注定会成为未来室内无线光通信的主角。提出了一种可见光局域网通信的模型,重点研究了基于无线光码分多址(WOCDMA)的信道共享方案。在以往的光正交码(OOC)基础上,采用了随机光码(random optical code)作为系统的扩频码,并对其相应的性能做了对比。

Research of wireless LAN based on visible light communication

The visible light communication has drawn increasing attention in indoor optical wireless LAN.Visible light communication with the transmit power required to apply for spectrum,electromagnetic interference,energy conservation,etc.,destined to become the protagonist of the indoor wireless optical communications.In this paper,a novel wireless LAN based On visible light communication was introduced.The paper focuses on the channel sharing scheme based on wireless optical code division multiple access(WOCDMA).On the basis of optical orthogonal code(OOC),using random optical code(ROC),and the corresponding performance was compared.
