Photonic Hybrid Precoding for Millimeter Wave RoF Systems
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. With help of silicon photonic integrated circuits (Si-PICs), the
photonic precoding strategy combats the large losses of mmwave and mitigates
inter-user interference. Simulation results show that the proposed model can
offer significant coding gains over conventional precoding systems.Comment: 6 PAGES, 2 FIG
