Dipl.-Ing. Thomas Kühne


Thomas Kühne is a Phd student at the CommIT chair and holds a university degree (5-year Dipl.-Ing. equivalent to a M.Sc.) from the University of Technology Dresden. He has already gained professional research experience while working 3 years for the Fraunhofer Heinrich-Hertz-Institute in Berlin Germany. At the  Heinrich-Hertz-Institute he focused on developing prototypes for mm-wave communication and measurement devices for mm-wave channels. Thus he is experienced in hardware and signal-processing design for complex systems with high data rates.

Since 2015 he works for the Communications and Information Theory Group of Prof. Caire and is also working towards his own PhD degree. At the Technische Universität Berlin he is part of a team developing an innovative Massive MIMO platform. This platform can be used to investigate different aspects of systems with large number of antennas like hybrid analog/digital signal processing for multi-user-MIMO, efficient signal processing for zero-forcing precoding and more.

Zusammenfassung Millimeter-wave systems are the next step to increase the data rate of 5G mobile communication networks. Hybrid analog-digital beamforming is one of the core technologies to enable millimeter-wave communication. Both the theoretical basics and the hardware design have been investigated in recent years. Current research projects like the European SERENA project strive to develop platforms to demonstrate the performance gain of complete systems. We present a simulation based analysis of a planned proof-of-concept system to evaluate the influence of design decisions and hardware impairments. We use a geometrybased stochastic channel simulator and simulate both certain hardware aspects and signal processing parts. We focus on the signal processing parts directly related to the hybrid architecture used for multi user MIMO precoding like the initial link acquisition and the data precoding. We use our own state-ofthe- art algorithms for these parts.
