EE Seminar| Non-Orthogonal Multiple Access: Basics, Challenges, and Some Recent Progress

Start Date: August 23, 2017
End Date: August 23, 2017

By Professor Md. Jahangir Hossain (School of Engineering, UBC Okanagan campus, Kelowna, BC, Canada)
 
Until very recently, the state-of-the-art wireless communications systems have been utilizing a variety of orthogonal multiple access (OMA) technologies, in which the resources are allocated orthogonally to multiple users. As a result, the information signals of users can be retrieved at a low complexity. Nonetheless, the number of served users is limited by the number of orthogonal resources. Conversely, non-orthogonal multiple access (NOMA) serves multiple users simultaneously using the same spectrum resources (i.e., radio channels), however, at the cost of increased intra-cell interference. To mitigate intra-cell interference, NOMA exploits Successive Interference Cancellation (SIC) at the receivers. NOMA is a potential access technology for 5G networks due to its improved spectral efficiency and low transmission latency. This tutorial will cover basics, some challenges, and recent progress of NOMA technology.
 
Biography: Md. Jahangir Hossain (S’04-M’08) received the B.Sc. degree in electrical and electronics engineering from Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh; the M.A.Sc. degree from the University of Victoria, Victoria, BC, Canada, and the Ph.D. degree from the University of British Columbia (UBC), Vancouver, BC, Canada. He is currently working as an Associate Professor in the School of Engineering, UBC Okanagan campus, Kelowna, BC, Canada. His research interests include designing spectrally and power-efficient modulation schemes, quality of service issues and resource allocation in wireless networks. Dr. Hossain regularly serves as a member of the Technical Program Committee of the IEEE International Conference on Communications (ICC). Currently, he is serving as an Editor for the IEEE Communications Surveys and Tutorials and he was an Editor for the IEEE Transactions on Wireless Communications.
