DSP enabled Fiber-Wireless IFoF/mmWave link for 5G Analog Mobile Fronthaul

An Analog RoF-based Mobile Fronthaul architecture compatible to 5G requirements is presented. Experimental demonstration of 24 Gb/s IFoF transmission based on Digital Subcarrier Multiplexing technique is reported using a centralized DSP unit. Combined with 60 GHz radio equipment, successful indoor uplink/downlink experiments are demonstrated using Single Carrier QPSK/16-QAM achieving up to 4 Gb/s total capacity over a fiber/wireless link.
