用于大规模MIMO可见光通信的空间调制技术

摘要
可见光(Visible Light Communication,VLC)通信作为无线通信的一个全新手段,引起了国内外研究者的广泛关注,是今后研究光无线通信的一个重要方向.基于发光二极管(LED)的可见光通信将照明和数据通信融合到应用中,能够实现高能效,高频谱效率以及相对较好的安全性和可靠性.而大规模多输入多输出(MIMO)更是具有提高可见光通信(VLC)系统传输速率的巨大潜力.然而,高通道间干扰(ICI)是严重影响传输性能的主要因素.在本文中,利用发射机处已知的信道状态信息(CSI),通过分析MIMO-VLC的特殊特征,提出了可见光链路容忍集调度算法(LTS-MIMO),并且对它们进行最优调度,以提高网络的吞吐量从而达到最大化网络性能的目的.
As a further means of wireless communication, Visible Light Communication(VLC) has attracted compelling attentions from researchers, and is also an important direction on studying optical wireless communication in the future. Light-emitting diode(LED)-based visible light communication combines lighting and data communications into applications, energy efficiency, high spectral efficiency, and relatively good security and reliability are realized. Massive multiple-input multiple-output(MIMO) has great potential to increase the transmission rate of visible light communication systems. However, inter channel interference(ICI) is a major factor that seriously affects transmission performance. In this paper, by using the known channel state information(CSI) at the transmitter, and analyzing the special characteristics of MIMO-VLC, the visible link tolerant set scheduling algorithm(LTS-MIMO) is proposed. And the network throughput and network performance are improved by optimizing the scheduling.
