Keynote 2

Millimeter Wave MIMO Signal Processing Robert W. Heath Professor, IEEE Fellow The University of Texas at Austin, USA Abstract Millimeter wave has become an incubator for the rebirth of MIMO communication. It has many applications, as a core 5G technology, and also as a conduit for emerging applications of wireless to fixed access, vehicular, aerial, and wearable networks. In this talk, I explain why communication at millimeter wave - and even higher frequencies - is interesting from a signal processing perspective. I first describe the three differentiating features of communication at millimeter wave: larger arrays, new channel models, and power constraints. Then I explain how these features impact the formulation and solution of traditional MIMO signal processing problems like beamforming, precoding, and channel estimation. I describe the signal processing challenges associated with fast antenna array configuration. In particular, I highlight how out-of-band information, sensing, and machine learning algorithms can reduce the overhead in tasks such as adaptive channel estimation and beamforming. I conclude with directions for future research. Biography Robert W. Heath Jr. received the Ph.D. in EE from Stanford University.
