Abstract
In this work, a design for a multiple input-multiple output (MIMO) visible light communication (VLC) system is proposed, based on the optical code division multiple access (OCDMA) technique. The proposed design possess the capability of operating in the low signal-to-noise (SNR) regime, due to the multiplexing gain obtained from the MIMO technique and the processing gain obtained from the OCDMA technique. Simulation results show that, the proposed system is capable of achieving the forward error correction (FEC) bit error rate (BER) limit of 10 −3 , while operating at SNR values as low as −1 dB. Accordingly, the reported design is recommended for VLC systems that employ very low sensitivity optical photo-detectors.
