Abstract: Communication at millimeter wave (mmWave) frequencies is defining a new era of wireless communication. The mmWave band offers much higher bandwidth communication channels than presently used in commercial wireless systems. Wireless local area networks are already exploiting the 60 GHz mmWave band, while 5G cellular systems are likely to operate at other mmWave frequencies. Because of the large antenna arrays, different channel models, and new hardware constraints, signal processing is different in mmWave communication systems. This short tutorial will provide an overview of mmWave wireless communication from a signal processing perspective. Topics covered include propagation models and the presence of sparsity in the channel, power consumption and resulting hardware constraints, MIMO techniques in mmWave including beam training, hybrid beamforming, MIMO with low-resolution analog-to-digital converters, and channel estimation. Millimeter wave communication is a topic of extreme interest right now in the signal processing and communication theory communities. We also note it is a significant area of interest for the US Government, with the FCC just releasing a notice of inquiry for using mmWave spectrum for mobile communication and suggesting potential spectrum. Bio: Nuria González Prelcic is currently an Associate Professor in the Signal Theory and Communications Department, University of Vigo, Spain. She has held visiting positions with the University of New Mexico (2011), and The University of Texas at Austin (2014, 2015 and 2016). Her main research interests include signal processing theory and signal processing for wireless communications: filter banks, compressive sampling and estimation, multicarrier modulation, channel estimation and MIMO processing for millimeter wave communications. In the last 3 years she has co-authored around 30 journal and conference papers in the topic of signal processing for MIMO systems with large arrays. She has published a tutorial in the IEEE Journal of Selected Topics in Signal Processing. She has also served as guest editor for the special issue of this journal on signal processing for mmWave wireless communications and is currently an Associate Editor for IEEE Transactions on Wireless Communications. She has delivered tutorials on millimeter wave communications at Globecom 2016, WCNC 2017 and ICASSP 2017. She has been the founding director of the Atlantic Research Center for Information and Communication Technologies (AtlantTIC) at the University of Vigo from 2010 to 2017.
