Joint Beamforming and PD Orientation Design for Mobile Visible Light Communications [PDF]
IEEE Transactions on Wireless Communications, 2022 In this paper, we propose joint beamforming and photo-detector (PD) orientation (BO) optimization schemes for mobile visible light communication (VLC) with the orientation adjustable receiver (OAR). Since VLC is sensitive to line-of-sight propagation, we
