Mathematical Methods for Multi-antenna Wireless Communications
Speaker: Dr. Amine Maaref
Faculty Host: Professor Francisco De Leon
Wireless systems are undergoing a massive shift from the traditional one-dimensional single-antenna transmission paradigm to a more sophisticated one relying on multiple-input multiple-output (MIMO) antenna technology and cooperative communications. In this talk, we will see how mathematical methods notably based on random matrix theory can be leveraged to derive crucial performance metrics for wireless systems operating under various frequency-flat fading channels. Both fundamental capacity limits and realistic multi-antenna strategies are analyzed based on the theory of finite dimensional random matrices. We show how the problem of characterizing the performance of three intrinsically different MIMO transmission schemes over wireless fading channels, namely, orthogonal space-time block coding, transmit-beamforming and spatial multiplexing, turns out to be closely related to the stochastic properties of the channel matrix in general and to the eigenvalue distributions of a certain class of random matrices in particular. By capitalizing on the strong correlation between these random matrices and MIMO systems, we are able to create a framework for the performance evaluation of adaptive and non-adaptive transmission techniques over MIMO fading channels.

Prior to joining Huawei, he held several research positions both in academia and industry, notably as a Natural Sciences and Engineering Research Council of Canada (NSERC) Postdoctoral Research Fellow with the department of Electrical & Computer Engineering, University of British Columbia, Vancouver, BC, Canada, a Research Scientist with Mitsubishi Electric Research Labs (MERL), Cambridge, MA, USA and a Senior Scientist with Etisalat British Telecom Innovation Center (EBTIC), Abu Dhabi, UAE.
Amine received the BSc (Eng.) degree (with high distinction) from Sup’Com, Tunis, Tunisia, and the MASc and PhD degrees from INRS-EMT, University of Quebec, Montreal, QC, Canada, all in
Telecommunications. He has expertise in several areas of wireless and mobile communications and networks, including radio resource management in next generation networks, interference management and coordination in cellular networks, beamforming and interference mitigation, performance analysis and cross-layer design for wireless MIMO systems, virtual MIMO and cooperative communications, network coding, cognitive radio, communication and information theories. He has co-authored more than 40 international peer-reviewed publications with a high citation index and several patent disclosures in the relevant areas. During his time at MERL, he was actively involved in the 3GPP LTE/LTE-Advanced and WiMAX IEEE 802.16m radio access network standardization bodies.
Dr. Maaref is the recipient of the Banting Fellowship at Princeton University (2011-2013), the Best Paper Award at IEEE WCNC 2010, Sydney, Australia, the 2008 ADESAQ Prize of Excellence for the best Ph.D. thesis in all disciplines of engineering and natural sciences across all universities in the Province of Quebec, Canada. He also received a number of prestigious awards for his outstanding scholar achievements including the Tunisian government scholarship of Excellence for pursuing postgraduate studies in Canada (2002-2007), the IEEE Communications Society (ComSoc) Student Travel Grant (three times), the Canadian Wireless Telecommunications Association (CWTA) Scholarship (2004-2005), the Alexander Graham Bell Canada Graduate Scholarship (2005-2007), the Rene-Fortier Bell Canada Graduate Scholarship (2006-2008), the NSERC and FQRNT Postdoctoral Fellowships (2007-2009). He regularly serves on the TPC boards of prominent IEEE ComSoc conferences such as ICC, GLOBECOM and WCNC and chairs some of their technical sessions.
