Fibre/Wireless convergence for 5G Front/Back-hauling

TeCIP Institute - 18th October 2019 – Blue Room – 14:00

Abstract:

This seminar is regarding the presentation of the research activities on fibre/wireless(Fi-Wi) convergence for 5G fronthaul, midhaul and backhaul, operating in microwave and millimeter (mm-waves) with throughput of up to 20 Gbps. Implementations of novel architectures for multiband 5G FiWi systems, applied to enhanced mobile broadband (eMBB) and new vertical applications, are going to be reported and discussed into details. Our radio over fiber-based fronthaul solution uses a WDM-PON infrastructure, from a commercial Internet service provider, to enable 5G operation over multiple frequency bands, including: a DSP and flexible waveform-based signal at 788 MHz, which can be set as generalized frequency division multiplexing (GFDM) or filtered orthogonal frequency division multiplexing (F-OFDM); 5G new radio (NR) signals at 3.5 or 26 GHz in accordance to 3GPP Release 15; an additional vector 26 GHz signal with bandwidth of up to 800 MHz. The DSP-based functionality provides digital pre-distortion (DPD), besides the real-time waveform generation.

Short bio:

Prof. Dr. Arismar Cerqueira S. Jr. received his Ph.D. degree from Scuola Superiore Sant’Anna-Italy in 2006. He was Invited Researcher and Professor from many world-recognized universities, such as University of Oulu (2017), Scuola Superiore Sant’Anna-Italy (2015 and 2017), Danish Technical University-Denmark (2013), Max-Planck Institute-Germany (2010) and University of Bath-UK (2004, 2005 and 2007). He was Associate Professor from the State University of Campinas (Unicamp) from March 2009 to August 2011, when he joined the National Institute of Telecommunications (Inatel) from Brazil to work in the same position. He has large experience on optical-wireless communications, microwave photonics, radio over fiber systems, mm-waves systems, reconfigurable antenna arrays and wireless systems Since 2009 he has been acting as a Coordinator of R&D Projects on diverse areas of telecommunications, including Antennas, 5G Networks, Radars and Microwave Photonics. He is a holder of 10 patents, has transferred 19 products to the industry and has published 232 scientific papers.
