Imaging-MIMO visible light communication system using μLEDs and integrated receiver

Multiple-input multiple-output (MIMO) transmission can be used to increase the throughput of visible light communication (VLC) systems. This approach is highly compatible with the use of arrays of micro light emitting diodes (μLEDs). In this work, we demonstrate an imaging-MIMO VLC system using a two dimensional individually addressable array of μLEDs and an integrated CMOS-based receiver. An aggregate data rate of -920 Mbps is realized using four parallel channels at a link distance of 1 m. Further improvement in the data rates is feasible by optimizing the system components and operating conditions.
