Non-Orthogonal Multiple Access (NOMA) for Downlink Multiuser MIMO Systems: User Clustering, Beamforming, and Power Allocation
Md Shipon Ali, Ekram Hossain, Dong In Kim
We investigate the application of non-orthogonal multiple access (NOMA) with successive interference cancellation (SIC) in downlink multiuser multiple-input multiple-output (MIMO)…
Modeling and Analysis of Uplink Non-Orthogonal Multiple Access (NOMA) in Large-Scale Cellular Networks Using Poisson Cluster Processes
Hina Tabassum, Ekram Hossain, Md. Jahangir Hossain
Non-orthogonal multiple access (NOMA) serves multiple users by superposing their distinct message signals. The desired message signal is decoded at the receiver by applying success…
Minority Games With Applications to Distributed Decision Making and Control in Wireless Networks
Shermila Ranadheera, Setareh Maghsudi, Ekram Hossain
Fifth generation (5G) dense small cell networks (SCNs) are expected to meet the thousand-fold mobile traffic challenge within the next few years. When developing solution schemes f…
Non-Orthogonal Multiple Access (NOMA) in Cellular Uplink and Downlink: Challenges and Enabling Techniques
Hina Tabassum, Md Shipon Ali, Ekram Hossain +2
By combining the concepts of superposition coding at the transmitter(s) and successive interference cancellation (SIC) at the receiver(s), non-orthogonal multiple access (NOMA) has…
LTE/LTE-A Random Access for Massive Machine-Type Communications in Smart Cities
Md Shipon Ali, Ekram Hossain, Dong In Kim
Massive Machine-Type Communications (MTC) over cellular networks is expected to be an integral part of wireless "Smart City" applications. The Long Term Evolution (LTE)/LTE-Advance…
Dynamic User Clustering and Power Allocation for Uplink and Downlink Non-Orthogonal Multiple Access (NOMA) Systems
Md Shipon Ali, Hina Tabassum, Ekram Hossain
In this paper, first we briefly describe the differences in the working principles of uplink and downlink NOMA transmissions. Then, for both uplink and downlink NOMA, we formulate…
