Fairness Enhancement of UAV Systems with Hybrid Active-Passive RIS
Nhan Thanh Nguyen, Van-Dinh Nguyen, Hieu Van Nguyen +4
We consider unmanned aerial vehicle (UAV)-enabled wireless systems where downlink communications between a multi-antenna UAV and multiple users are assisted by a hybrid active-pass…
Optimization of Rate Fairness in Multi-Pair Wireless-Powered Relaying Systems
Van-Phuc Bui, Van-Dinh Nguyen, Hieu V. Nguyen +2
This letter considers a multi-pair decode-and-forward relay network where a power-splitting (PS) protocol is adopted at the energy-constrained relay to provide simultaneous wireles…
A New Design Paradigm for Secure Full-Duplex Multiuser Systems
Van-Dinh Nguyen, Hieu V. Nguyen, Octavia A. Dobre +1
We consider a full-duplex (FD) multiuser system where an FD base station (BS) is designed to simultaneously serve both downlink (DL) and uplink (UL) users in the presence of half-d…
Joint Beamforming and Antenna Selection for Sum Rate Maximization in Cognitive Radio Networks
Van-Dinh Nguyen, Chuyen T. Nguyen, Hieu V. Nguyen +1
This letter studies joint transmit beamforming and antenna selection at a secondary base station (BS) with multiple primary users (PUs) in an underlay cognitive radio multiple-inpu…
Spectral Efficiency of Full-Duplex Multiuser System: Beamforming Design, User Grouping, and Time Allocation
Van-Dinh Nguyen, Hieu V. Nguyen, Chuyen T. Nguyen +1
Full-duplex (FD) systems have emerged as an es- sential enabling technology to further increase the data rate of wireless communication systems. The key idea of FD is to serve mult…
