摘要
本文提出一种基于可见光通信混合的组网方案,该方案中下行数据由LED阵列发送,上行数据通过Wi-Fi网络发送。基于该混合组网,还提出一种室分复用机制,实现了多房间之间的室内宽带通信。通过该室分复用机制,混合可见光通信网络的吞吐量可得到显著提高。此外该混合组网中还可实现用户的定位和主动切换。实验平台验证了该混合组网的架构、室分复用和主动切换算法。
This paper puts forward a networking scheme based on hybrid visible light communication. In this scheme, downlink data is sent by LED array and the uplink data is sent by the Wi-Fi network. Based on this hybrid networking, there also comes up with a kind of Rooms Division Multiplexing mechanism, which realizes the indoor broadband communication among multi rooms. The throughput capacity of hybrid visible light communication network can be remarkably enhanced by this Rooms Division Multiplexing mechanism. Besides, this hybrid networking is also able to locate the users and handover actively. The structure of this hybrid networking and the algorithm of Rooms Division Multiplexing and active handover are proved by the experimental platform.
