Rate Maximization for Downlink Multiuser Visible Light Communications
IEEE Access, 2016 We are interested in optimizing transmit beamforming for a visible light communication multiuser system such that the achievable sum rate is maximized. We first derive a closed-form sum rate expression via information-theoretic tools.
