10:30 a.m. ENGR, room 103. Ph.D. Candidate Mojtaba Ahmadi Almasi from Boise State University will be the speaker for the seminar “Reconfigurable Antennas in mmWave MIMO Systems”. Mojtaba Ahmadi Almasi received his B.Sc. degree as a first class honor in Electrical Engineering from Uremia University in Uremia, Iran in 2010. From 2010 to 2012, he was an M.Sc. student at Iran University of Science and Technology (IUST), Tehran, Iran. After graduating, he was an active researcher in wireless communications focusing on space-time block codes. His current research interests are wireless communications and signal processing with emphasis on mmWave communication systems.
The large spectrum available in the millimeter-Wave (mmWave) band has emerged as a promising solution for meeting the huge capacity requirements of the fifth generation (5G) wireless networks. However, to fully harness the potential of mmWave communications, obstacles such as severe path loss, channel sparsity and hardware complexity should be overcome. In this presentation, Almasi will address the existence of mmWave structures. Further, a generalized reconfigurable antenna multiple-input multiple-output (MIMO) architecture will be represented. This MIMO takes advantage of lens-based reconfigurable antennas. The considered antennas can support multiple radiation patterns simultaneously by using a single RF chain. On the other hand, non-orthogonal multiple access (NOMA) is an essential enabling technology for the 5G wireless networks to meet the heterogeneous demands. By using NOMA in mmWave systems the number of supported users can be larger than the RF chains.
