提供高数据速率是可见光通信(VLC)系统中最大的关注点之一。本文介绍了一种使用VLC系统进行下行通信的数据中心设计。在这项工作中,RYGB激光二极管(LD)被用作发射器,以获得高的调制带宽。采用宽视场接收机(WFOVR)、三分支角度分集接收机(ADR)和50像素成像接收机(ImR)三种接收机对延迟扩展和信噪比进行了测试。该系统采用简单的开关键控(OOK)调制实现了高达14.2 Gbps的数据速率。
Providing high data rates is one of the big concerns in visible light communication (VLC) systems. This paper introduces a data centre design that use a VLC system for downlink communication. In this work, RYGB laser diodes (LD) are used as transmitters to obtain a high modulation bandwidth. Three types of receivers, wide field of view receiver (WFOVR), 3 branches angle diversity receiver (ADR) and 50 pixels imaging receiver (ImR) are used to examine delay spread and SNR. The proposed system achieved data rates up to 14.2 Gbps using simple on-off-keying (OOK) modulation.
