Abstract

This letter reports a demonstration of a 2×2 multiple- input multiple-output (MIMO) indoor visible-light communication (VLC) system using a novel fluorescent optical concentrator based receiver. This potentially allows a high degree of spatial multiplexing to be achieved using a simple receiver structure that can have a wide field-of-view (FOV). Details of a two-channel MIMO VLC system that operates at 32 Mbps with a receiver acceptance angle of ±22.5° are given, and future directions discussed.
