A Novel Heap-based Pilot Assignment for Full Duplex Cell-Free Massive MIMO with Zero-Forcing
Hieu V. Nguyen, Van-Dinh Nguyen, Octavia A. Dobre +4
This paper investigates the combined benefits of full-duplex (FD) and cell-free massive multiple-input multipleoutput (CF-mMIMO), where a large number of distributed access points…
Dynamic User Pairing for Non-Orthogonal Multiple Access in Downlink Networks
Kha-Hung Nguyen, Hieu V. Nguyen, Van-Phuc Bui +1
This paper considers a downlink (DL) system where non-orthogonal multiple access (NOMA) beamforming and dynamic user pairing are jointly optimized to maximize the minimum throughpu…
UAV-Assisted Secure Communications in Terrestrial Cognitive Radio Networks: Joint Power Control and 3D Trajectory Optimization
Phu X. Nguyen, Van-Dinh Nguyen, Hieu V. Nguyen +1
This paper considers secure communications for an underlay cognitive radio network (CRN) in the presence of an external eavesdropper (Eve). The secrecy performance of CRNs is usual…
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…
