Full-duplex coherent analogue mm-wave RoF transmission with simplified RRH and photonic down-conversion of uplink

Abstract

We demonstrate full-duplex analogue transmission of mm-wave radio at 29.3/34.3GHz using an EML to simultaneously perform coherent downlink detection and uplink transmission at the RRH. We further introduce photonic down-conversion of the uplink to simplify its frequency translation while eliminating dispersion-induced fading over 15km reach.
