RIS-enabled Multi-user M-QAM Uplink NOMA Systems: Design, Analysis, and Optimization
Mahmoud AlaaEldin, Mohammad Al-Jarrah, Xidong Mu +3
Non-orthogonal multiple access (NOMA) is widely recognized for enhancing the energy and spectral efficiency through effective radio resource sharing. However, uplink NOMA systems f…
Fed-Sophia: A Communication-Efficient Second-Order Federated Learning Algorithm
Ahmed Elbakary, Chaouki Ben Issaid, Mohammad Shehab +3
Federated learning is a machine learning approach where multiple devices collaboratively learn with the help of a parameter server by sharing only their local updates. While gradie…
Generalized BER Performance Analysis for SIC-based Uplink NOMA Systems
Mahmoud AlaaEldin, Emad Alsusa, Mohammad Al-Jarrah +1
Non-orthogonal multiple access (NOMA) is widely recognized for its spectral and energy efficiency, which allows more users to share the network resources more effectively. This pap…
Optimization of Energy-Constrained IRS-NOMA Using a Complex Circle Manifold Approach
Mahmoud AlaaEldin, Emad Alsusa, Karim G. Seddik +2
This work investigates the performance of intelligent reflective surfaces (IRSs) assisted uplink non-orthogonal multiple access (NOMA) in energy-constrained networks. Specifically,…
