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…
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…
Analysis of SINR Outage in Large-Scale Cellular Networks Using Campbell's Theorem and Cumulant Generating Functions
Sudarshan Guruacharya, Hina Tabassum, Ekram Hossain
The signal-to-noise-plus-interference ratio (SINR) outage probability is one of the key performance parameters of a wireless cellular network, and its analytical as well as numeric…
On User Association in Multi-Tier Full-Duplex Cellular Networks
Ahmed Hamdi Sakr, Ekram Hossain
We address the user association problem in multi-tier in-band full-duplex (FD) networks. Specifically, we consider the case of decoupled user association (DUA) in which users (UEs)…
Distributed User Association in Energy Harvesting Small Cell Networks: A Probabilistic Model
Setareh Maghsudi, Ekram Hossain
We consider a distributed downlink user association problem in a small cell network, where small cells obtain the required energy for providing wireless services to users through a…
