"Robust Multiuser MIMO Transceiver Design Under Channel Uncertainty"
by Michael Botros Shenouda, Timothy N. Davidson, Lutz Lampe


Employing multiple antennas in multiuser communication systems has the potential to increasing the achieved data rates and improving the overall system performance. However, many of these potential gains depend on the amount of channel state information available (CSI) at both the transmitter and the receiver. In many systems, the CSI that is available at the transmitter suffers from inaccuracies that are caused by errors in channel estimation and/or limited, delayed or erroneous feedback, and the performance of many multiuser systems are particularly sensitive to uncertainties in the CSI. These uncertainties can result in multiuser systems that are dominated by interference, and hence in a significant degradation of the quality of service (QoS) offered to the users and their data rates. Due to the inevitability of imperfect CSI, robust communication schemes that take into account the channel uncertainty are of interest in practice. The goal of the tutorial is to provide a unified exposition of the theoretical results regarding efficient design of multiuser systems that explicitly take into account these uncertainties. This unification is provided through the theories of robust and convex optimization. It will be demonstrated that by incorporating robustness in the design one can significantly reduce the sensitivity of multiuser systems to channel uncertainties and mitigate their deleterious effects.


Michael Botros Shenouda received the B.Sc. (Hons. 1) degree and the M.Sc. degree in Electrical Engineering from Cairo University in 2001 and 2003, respectively. He received the Ph.D. degree from McMaster University, Canada in 2008. His main areas of interest include wireless and MIMO communication, robust and convex optimization, and signal processing algorithms. He is also interested in majorization theory and its application in the unification of designs for non-linear MIMO transceivers.
Mr. Botros Shenouda was awarded an IEEE Best Student Paper Award at ICASSP 2006, and was also a finalist in the IEEE Best Student Paper competition at ICASSP 2007. He was the recipient of two provincial scholarships during his PhD degree. Dr. Botros Shenouda has also received the National Science and Engineering Council of Canada (NSERC) Postdoctoral Fellowship, and he holds Killam Postdoctoral Fellowship at the University of British Columbia.
