Prof. Torbjorn Ekman received his M.Sc. degree in engineering physics in 1994 and his Ph.D. degree in signal processing in 2002, both from Uppsala University, Sweden. From 1997 to 1998 he was a visiting scientist at the Institute of Communications and Radio-Frequency Engineering, Vienna University of Technology, Vienna, Austria, on a Marie Curie Grant. From 1999 to 2002, he visited the Digital Signal Processing Group at the University of Oslo, Norway. In 2002–2005, he completed his postdoctoral studies at UniK, University Graduate Center, Kjeller, Norway. In 2006 he joined the Department of Electronic Systems of the Norwegian University of Science and Technology—NTNU in Trondheim, Norway, where he is a professor in the Department of Electronic Systems. His research interests include signal processing in wireless communications, microsatellite communication, Massive MIMO and dynamic radio channel modeling. He is currently responsible for the national infrastructure project Reconfigurable Radio Network Platform (ReRaNP) for massive MIMO research.
