Christoph Studer received his Ph.D. degree in 2009 from ETH Zurich, and he was a postdoctoral researcher at ETH Zurich and Rice University from 2009 to 2013. Since 2014, Dr. Studer has been an Assistant Professor at Cornell University in the School of Electrical and Computer Engineering and an Adjunct Professor at Rice University. In July 2019, Dr. Studer transferred to Cornell Tech in New York City where he is now an Associate Professor. Dr. Studer’s research is at the intersection of communication theory, signal processing, and digital integrated circuit design. He received ETH Medals for his M.S. and Ph.D. theses, a two-year Swiss National Science Foundation fellowship for Advanced Researchers, and a US National Science Foundation CAREER Award. He has won several best-paper and live demonstration awards at international conferences, and he has received the Swisscom/ICTnet Innovations Award twice.
Low-Resolution to the Rescue for All-Digital mmWave Massive MIMO
Massive multiple-input multiple-output (MIMO) combined with mmWave communication will be a key technology component of future wireless systems. While massive MIMO enables high spectral efficiency via fine-grained beamforming and mmWave communication provides extremely large bandwidths, naïve 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. In this talk, we demonstrate that reliable communication is feasible with all-digital basestation architectures when combining low-resolution data converters with low-resolution baseband processing, while significantly reducing system costs, power consumption, and interconnect data rates.
