Distributed MIMO Signal Transmissions for 5G Mobile Communications Networks


Emil Björnson

Abstract

Over the past decade, Massive MIMO has gone from being a wild multi-antenna concept for improving the data rates in future cellular networks to mainstream technology. It is about time to look for the next big improvement in the physical layer. Two concepts that have recently received increasing attention are software-controlled metasurfaces and holographic beamforming, which are also known as intelligent reflective surfaces and large intelligent surfaces. In this talk, we will go through the basics of these concepts, recent results, and also what the potential performance gains might be - which are not as obvious as it might seem.



Biography
Emil BjoernsonEmil Björnson

Emil Björnson received the M.S. degree in engineering mathematics from Lund University, Sweden, in 2007, and the Ph.D. degree in telecommunications from the KTH Royal Institute of Technology, Sweden, in 2011. From 2012 to 2014, he held a joint post-doctoral position at the Alcatel-Lucent Chair on Flexible Radio, SUPELEC, France, and the KTH Royal Institute of Technology. He joined Linköping University, Sweden, in 2014, where he is currently an Associate Professor and a Docent with the Division of Communication Systems.
He has authored the textbooks "Optimal Resource Allocation in Coordinated Multi-Cell Systems" (2013) and "Massive MIMO Networks: Spectral, Energy, and Hardware Efficiency" (2017). He is dedicated to reproducible research and has made a large amount of simulation code publicly available. He has performed MIMO research for 15 years and has filed more than 20 MIMO-related patent applications. He has received the 2014 Outstanding Young Researcher Award from IEEE ComSoc EMEA, the 2015 Ingvar Carlsson Award, the 2016 Best Ph.D. Award from EURASIP, the 2018 IEEE Marconi Prize Paper Award in Wireless Communications, the 2019 EURASIP Early Career Award, and the 2019 IEEE Communications Society Fred W. Ellersick Prize. He also co-authored papers that received Best Paper Awards at the conferences, including WCSP 2009, the IEEE CAMSAP 2011, the IEEE WCNC 2014, the IEEE SAM 2014, the IEEE ICC 2015, and the WCSP 2017.
