A 2×2 imaging MIMO system based on LED Visible Light Communications employing space balanced coding and integrated PIN array reception

• A MIMO-VLC system by using space balanced coding based on PIN array reception.
• . The data rate is 1.4-Gbit/s at a distance of 2.5m.
• The system overcomes the limitation of bandwidth existing in LEDs.

In this paper, we proposed a 2×2 imaging Multi-Input Multi-Output (MIMO)-Visible Light Communication (VLC) system by employing Space Balanced Coding (SBC) based on two RGB LEDs and integrated PIN array reception. We experimentally demonstrated 1.4-Gbit/s VLC transmission at a distance of 2.5 m. The proposed imaging system not only overcomes the limitation of bandwidth existing in LEDs, but also can reject the second-order nonlinearity distortion. It turned out to be very promising to use integrated antennas in the VLC system in the future.
