Beam Selection in Millimeter-wave Multi-user MIMO Communications

Millimeter wave (mmWave) frequencies offers huge transmission bandwidths and allows packing a large number of antennas within a given aperture area, enabling massive MIMO communications. However, a major bottleneck in realizing such systems is the requirement of a large number of RF chains. Working in the beamspace (i.e., angular) domain provides an attractive solution to this problem through beam selection. In this talk, we discuss different beam selection algorithms; In particular, we present a matching theoretic framework for beam selection, based on the concepts of two-sided stable matching, developed in the field of Economics.

Dr. K. V. Srinivas's Bio

K. V. Srinivas received his M.Tech degree from IIT Kanpur and Ph.D from IIT Madras, both in Electrical Engineering. He was a Postdoctoral Fellow at the Department of Electrical and Computer Engineering, University of Toronto, Canada, from March 2009 to October 2011. His industry experience includes working with Indian Space Research Organisation, Samsung Electronics and Nokia Networks. Since January 2015, he is an Assistant Professor at IIT (BHU), Varanasi. His research interests are in wireless communications, focusing on physical and MAC layer algorithms, and statistical learning theory. Currently he is at Dalhousie University, Canada, as a visiting researcher.

Dr. Srinivas will deliver his talk over Skype from Dalhousie University in Canada
