Controlling Smart Propagation Environments: Long-Term versus Short-Term Phase Shift Optimization
Trinh Van Chien, Lam Thanh Tu, Dinh-Hieu Tran +4
Reconfigurable intelligent surfaces (RISs) have recently gained significant interest as an emerging technology for future wireless networks. This paper studies an RIS-assisted prop…
Optimal User Pairing for Achieving Rate Fairness in Downlink NOMA Networks
Van-Phuc Bui, Phu X. Nguyen, Hieu V. Nguyen +2
In this paper, a downlink non-orthogonal multiple access (NOMA) network is studied. We investigate the problem of jointly optimizing user pairing and beamforming design to maximize…
On the Design of Secure Full-Duplex Multiuser Systems under User Grouping Method
Van-Dinh Nguyen, Hieu V. Nguyen, Octavia A. Dobre +1
Consider a full-duplex (FD) multiuser system where an FD base station (BS) is designed to simultaneously serve both downlink users and uplink users in the presence of half-duplex e…
