Title: From MIMO to Large-scale MIMO

Abstract: Multiple-input multiple-output (MIMO) communications systems have been seriously considered in recent years to achieve substantial gains in spectral, power, and energy efficiency compared to conventional single-input single-output (SISO) systems. Various MIMO configurations based on Single-User (SU)-MIMO, Multi-User (MU)-MIMO, network-MIMO architectures have been proposed for LTE systems. To accommodate the ever-increasing demands of different multimedia services and applications, the evolving next-generation wireless access networks are envisioned to support 1,000-fold gains in capacity, connections for billions of diverse devices, and Gb/s individual user data rates. Large-scale MIMO has emerged as a promising technology to deal with such challenges. Through the use of an excessively large number of service antennas in a fully coherent and adaptive operation, transmission and reception of signal energy can be focused into small regions to offer large improvements in throughput and energy efficiency, especially when combined with multi-user scheduling and in mmWave bands. Furthermore, large-scale MIMO can enhance the robustness to interference and intentional jamming.

The talk will provide an overview from MIMO, SU-MIMO, MU-MIMO, network-MIMO to large-scale MIMO developments applicable to next-generation wireless access communications, and highlight various technical issues and solutions along with our current research activities and recent results.


Bio: Tho Le-Ngocobtained his B.Eng. (with Distinction) in Electrical Engineering in 1976, his M.Eng. in Microprocessor Applications in 1978 from McGill University, Montreal,and his Ph.D. in Digital Communications 1983 from the University of Ottawa, Canada.

During 1977-1982, he was with Spar Aerospace Limited as a Design Engineer and then a Senior Design Engineer, involved in the development and design of the microprocessor-based controller of Canadarm (of the Space Shuttle), and SCPC/FM, SCPC/PSK, TDMA satellite communications systems.

During 1982-1985, he was an Engineering Manager of the Radio Group in the Department of Development Engineering of SRTelecom Inc., developed the new point-to-multipoint DA-TDMA/TDM Subscriber Radio System SR500. He was the System Architect of this first digital point-to-multipoint wireless TDMA system.

During 1985-2000, he was a Professor in the Department of Electrical and Computer Engineering of Concordia University.

Since 2000, he has been a Professor in the Department of Electrical and Computer Engineering of McGill University.

His research interest is in the area of broadband access communications.

Since 2004, he has been Scientific Director of the Center for Advanced Systems and Technologies in Communications (SYTACom), including 5 universities in Quebec.

He is a Senior Member of the Ordre des Ingénieur du Quebec, a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), the Engineering Institute of Canada (EIC), the Canadian Academy of Engineering (CAE), and the Royal Society of Canada (RSC). 

He is a recipient of the 2004 Canadian Award in Telecommunications Research, the IEEE Canada Fessenden Award 2005, and the 2013 Queen Elizabeth II Diamond Jubilee Medal.

He holds a Canada Research Chair (Tier I) onBroadband Access Communications.

He is a theme leader and/or project leader in three interdisciplinary NSERC Strategic Research Networks: Healthcare Support through Information Technology Enhancement (hSITE), NSERC Smart Microgrid Network (NSMG-Net), and Smart Applications on Virtual Infrastructure (SAVI).

Since 1985, he has been a consultant, Technical Advisor, Chief Architect, Chief Scientist to several companies in communications.
