title: The Index-based Optical Spatial Modulation Scheme
in Optical MIMO
ispublished: pub
subjects: ECE
divisions: fac_fet
abstract: 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.
