Massive MIMO in Practice

Henrik Asplund received his M.Sc. degree from Uppsala University, Sweden, in 1996 and joined Ericsson Research, Stockholm, Sweden, in the same year. Since then he has been working in the field of antennas and propagation supporting pre-development and standardization of all major wireless technologies from 2G to 5G. His current research interests include antenna techniques, radio channel measurements and modelling, and deployment options for 5G including higher frequencies.George Jöngren is currently an expert in adaptive multi-antenna technologies at Ericsson. Starting with his Ph.D. studies in 1999, he has two decades of experience working with state-of-the-art techniques in the multi-antenna field. He joined Ericsson in 2005 and has over the years had various roles, including working for eight years as a 3GPP delegate driving Ericsson's efforts on physical layer multi-antenna standardization. George Jöngren holds a Ph.D in signal processing and an M.Sc. in Electrical engineering from the Royal Institute of Technology, Stockholm, Sweden.Jonas Karlsson joined Ericsson in 1993. Since then he has held various technical and leader positions in Ericsson covering both radio access research and system management in product development. He is currently an Expert in Multi Antenna Systems at Development Unit Networks. He holds an M.Sc. in electrical engineering and engineering physics from Linköping University, Sweden, and a Ph.D. in electrical engineering from the University of Tokyo, Japan.Fredric Kronestedt joined Ericsson in 1993 to work on RAN research. Since then he has taken on many different roles, including system design and system management. He currently serves as Expert, Radio Network Deployment Strategies, at Development Unit Networks, where he focuses on radio network deployment and evolution aspects for 4G and 5G. Kronestedt holds an M.Sc. in electrical engineering from KTH Royal Institute of Technology, Stockholm, Sweden.Erik Larsson joined Ericsson in 2005. He is currently a researcher working with concept development and network performance for NR with a focus on advanced antenna systems. He holds both an M.Sc. in engineering physics and a Ph.D. in electrical engineering, specializing in signal processing, from Uppsala University, Sweden.David Astely is currently a Principal Researcher with Ericsson Research in the radio area. He received his Ph.D. in signal processing from KTH Royal Institute of Technology in 1999 and has been with Ericsson since 2001, where he has held various positions in both research and product development.Peter von Butovitsch joined Ericsson in 1994 and currently serves as Technology Manager at Systems & Technology. He has held various positions at Ericsson Research and in RAN system design over the years, and from 1999 to 2014 he worked for Ericsson in Japan and China. He holds both an M.Sc. in engineering physics and a Ph.D. in signal processing from KTH, Royal Institute of Technology in Stockholm, Sweden. In 2016, he earned an MBA from Leicester University in the UK. Peter von Butovitsch has served as the driver and main editor throughout the development of this book.Thomas Chapman is currently working within the radio access and standardization team within the Standards and Technology group at Ericsson. He has been contributing into 3GPP standardisation since 2000 to the whole portfolio of 3GPP technologies including UTRA TDD, WCDMA, HSPA, LTE and NR, and has been deeply involved in concept evaluation and standardization of AAS in RAN4. He holds an MSc (1996) and PhD (2000) in electronic engineering and signal processing from the University of Manchester, UK.
