Abstract. Multiple input multiple output (MIMO) transmission can be used to increase the capacity of visible light communication (VLC) systems. This approach is well compatible with the use of micro light emitting diode (µLED) arrays. In this paper, we demonstrate a VLC-MIMO imaging system using a 2D array of individually addressable microLEDs and an integrated CMOS-based receiver. The total data transfer rate of ~920 Mbps is realized using four parallel channels at a distance of 1 m. Further increase in data transfer rate is possible by optimizing the system components and operating conditions.
