Prof. Christoph Studer

Abstract: 

Massive multiple-input multiple-output (MIMO) will be a core technology of future millimeter-wave (mmWave) and terahertz (THz) wireless communication systems. The idea of massive MIMO is to equip the basestation with hundreds of antenna elements in order to serve tens of users in the same time-frequency resource. While this technology enables high spectral efficiency via fine-grained beamforming, naive implementations of all-digital basestation architectures with conventional data converters for each antenna element would result in excessively high system costs, power consumption, and interconnect data rates. This fact is further aggravated at mmWave/THz frequencies due to the extremely large bandwidths available for communication. In this talk, we demonstrate that reliable wideband communication is practically feasible with all-digital basestation architectures when combining low-resolution data converters with low-resolution baseband processing and sophisticated signal processing algorithms.
