ABSTRACT:
Massive MIMO (MaMI) has emerged as the most promising candidate technology for 5G, due to its ability to provide high spectral efficiency through spatial division multiple access (SDMA), at reasonable system complexity. However, it is not as well known is that SDMA, or multi-user MIMO (MU-MIMO), is already available as a feature in the first release of LTE (Long Term Evolution) back in 2010. So why is MaMI receiving such popular attention, even though it is simply one possible approach to implement MU-MIMO?
In this lecture, I will first explain the concept of MaMI as both a scaled up (number of antennas) and scaled down (transceiver complexity) version of conventional MU-MIMO, which result in it being particularly attractive for practical implementation. But in order for MaMI to deliver the promised performance gains at reasonably complexity, the most fundamental requirement is that the antennas and the propagation channel must provide the appropriate physical channel. I will relate this requirement to the desirable antenna characteristics and give several examples of practical MaMI antenna realizations.
Apart from playing an important role in MaMI base stations, the antenna system is no less important at the terminal side, to ensure high system performance. In this context, I will give my perspective on the development of terminal antenna system, including the current trends in terminal antenna design. I will then introduce a new antenna design paradigm that has the potential to dramatically improve system performance, not just for MaMI but also for other future systems.
BIOGRAPHY:
Buon Kiong Lau received the B.E. degree (with honors) from the University of Western Australia, Perth, Australia, and the Ph.D. degree from the Curtin University of Technology, Perth, Australia, in 1998 and 2003, respectively, both in electrical engineering. During 2000 to 2001, he was a Research Engineer with Ericsson Research, Kista, Sweden. From 2003 to 2004, he was a Guest Research Fellow at the Department of Signal Processing, Blekinge Institute of Technology, Sweden. Since 2004, he has been with the Department of Electrical and Information Technology, Lund University, where he is now a Professor in the Communications Group. He has held a Senior Researcher appointment with the Swedish Research Council from 2010 to 2019. He has been a Visiting Researcher with the Department of Applied Mathematics, Hong Kong Polytechnic University, China; the Laboratory for Information and Decision Systems, Massachusetts Institute of Technology, Cambridge, MA, USA; and the Takada Laboratory, Tokyo Institute of Technology, Japan.
Dr Lau's primary research interests are in various aspects of multiple antenna systems, particularly the interplay between antennas, propagation channels, and signal processing. He has co-authored 40 journal papers (20 in IEEE Transactions on Antennas and Propagation), 5 book chapters, over 100 conference papers and 3 patents/patent applications.
In 2015, Dr. Lau received an award from IEEE Transactions on Antennas and Propagation for exceptional performance as an Associate Editor (one of 3 awarded among 46 Associate Editors). His co-authored papers have received several Best Paper Awards, including two CST University Publication Awards in 2010 and 2013.
