Abstract
In this paper, we propose a multi-user (MU) multiple-input multiple-output (MIMO) optical orthogonal frequency division multiplexing (OOFDM) aided index modulation (IM) assisted indoor visible light communication (VLC) system. The IM principle is applied to the OOFDM scheme invoking block diagonalization based precoder (BDP) for a MU-VLC system, where a so-called data stream interleaver (SI) is introduced to further improve the system's performance. Simulation results show that the proposed hybrid MU-VLC system with SI is capable of outperforming its conventional counterparts in terms of bit error rate (BER) in indoor scenarios.
