Photonic Hybrid Precoding for Millimeter Wave RoF Systems
CoRR, 2017 Large propagation path loss and limited scattering of millimeter wave (mmwave) channels create new challenges for physical layer signal processing. Hence, in this article, we propose a photonic hybrid precoding model for mmwave radio-over-fiber systems that overcomes hardware constraints on radio frequency precoding.
