Stefan Wesemann received the Dipl.-Ing. (Masters) in Information Systems Engineering in 2006, and the Dr.-Ing. (PhD) in Electrical Engineering, both from Dresden University of Technology. Between 2007 and 2010, he worked for Signalion GmbH (now National Instruments) in 4G test equipment development. In 2014, Stefan joined the Next Generation Wireless Systems department at Nokia Bell Labs. His primary research focus are the massive MIMO implementation challenges in 4G and 5G systems, which include the acquisition of channel state information, advanced precoding methods for multi-user MIMO, novel antenna array architectures and back-/fronthauling solutions.
