description: Optical Multi-input Multi-output (O-MIMO) is  considered as an effective solution in order to achieve high  performance for Visible Light Communication (VLC) systems.  However, O-MIMO systems are faced with the impact of InterChannel Interference (ICI) which results in system performance  decrease. In this paper, a novel Index-based Optical Spatial  Modulation (IOSM) is proposed to remove ICI and increase  spectrum efficiency for indoor VLC systems applying O-MIMO.  In our proposed scheme, the signals are DC biased for intensity  modulation and direct detection (IM/DD) and a Maximumlikelihood (ML) decoder decision to maximize the signal-to-noise  ratio (SNR) at the receiver. Computer simulation results show  that the proposed scheme outperforms previously proposed  spatial modulation schemes in O-MIMO systems.
