论文摘要
提供很高数据速率的能力是光学无线通信(OWC)系统的重要好处。在本文中,设计了使用波长多访问(WDMA)的数据中心中的光学无线下行链路。红色,黄色,绿色和蓝色(RYGB)激光二极管(LDS)用作发射器,以提供高调制带宽。基于RYGB LDS的WDMA方案用于同时从同一光单元提供多个机架的通信。在本研究中检查了两种类型的光学接收器。具有三个分支和10像素成像接收器(IMR)的角度多样性接收器(ADR)。提出的数据中心在使用简单的开关钥匙(OOK)调制的同时,以较高的信噪比加噪声比(SINR)达到高数据速率。
The ability to provide very high data rates is a significant benefit of optical wireless communication (OWC) systems. In this paper, an optical wireless downlink in a data centre that uses wavelength division multiple access (WDMA) is designed. Red, yellow, green and blue (RYGB) laser diodes (LDs) are used as transmitters to provide a high modulation bandwidth. A WDMA scheme based on RYGB LDs is used to provide communication for multiple racks at the same time from the same light unit. Two types of optical receivers are examined in this study; an angle diversity receiver (ADR) with three branches and a 10 pixel imaging receiver (ImR). The proposed data centre achieves high data rates with a higher signal-to-interference-plus-noise ratio (SINR) for each rack while using simple on-off-keying (OOK) modulation.
