Abstract

In this paper, we consider multiple-input multipleoutput (MIMO) visible light communication (VLC) systems. The physical layer of VLC system builds upon optical orthogonal frequency division multiplexing (O-OFDM). Repetition code (RC), spatial multiplexing (SMUX) and spatial modulation (SMUD) are considered as MIMO techniques. We evaluate the performance of three MIMO O-OFDM VLC systems under consideration through the derivation of bit error rate expressions.
