Distributed MIMO Experiments for LiFi in a Conference Room
Abstract
Distributed multiple-input multiple-output (MIMO) techniques gain substantial interest for LiFi in indoor scenarios. Distributed MIMO provides homogeneous coverage, higher throughput, reduced blockage probability and lower latency. For developing efficient algorithms, profound knowledge about the optical channels and their MIMO properties are needful. In this paper, we have measured distributed MIMO channels for LiFi in a conference room and evaluated their capacity. Unlike RF, LiFi channels are mostly due to the line-of-sight. Here, we show that the MIMO channel matrix and capacity depend critically on the positions between transmitter and receiver pairs. Favorable and unfavorable configurations yield high and low capacity, respectively.
