He performs research on MIMO communications, radio resource allocation, machine learning for communications, energy-efficient communications, and future network design. He is on the editorial board of the IEEE Transactions on Communications (since 2017) and the IEEE Transactions on Green Communications and Networking (since 2016). He is the first author of the textbooks “Massive MIMO Networks: Spectral, Energy, and Hardware Efficiency” (2017) and “Optimal Resource Allocation in Coordinated Multi-Cell Systems” (2013). He is dedicated to reproducible research and has made a large amount of simulation code publicly available.

Dr. Björnson has performed MIMO research for more than ten years and has filed more than ten related patent applications. He received the 2019 IEEE Communications Society Fred W. Ellersick Prize, the 2019 EURASIP Early Career Award, the 2018 IEEE Marconi Prize Paper Award in Wireless Communications, the 2016 Best PhD Award from EURASIP, the 2015 Ingvar Carlsson Award, and the 2014 Outstanding Young Researcher Award from IEEE ComSoc EMEA. He also co-authored papers that received best paper awards at the conferences WCSP 2017, IEEE ICC 2015, IEEE WCNC 2014, IEEE SAM 2014, IEEE CAMSAP 2011, and WCSP 2009.
