Asymptotic Analysis of Max-Min Weighted SINR for IRS-Assisted MISO Systems with Hardware Impairments
Anastasios Papazafeiropoulos, Cunhua Pan, Ahmet Elbir +3
We focus on the realistic maximization of the uplink minimum signal-to-interference-plus-noise ratio (SINR) of a general multiple-input single-output (MISO) system assisted by an i…
Hybrid Relay-Reflecting Intelligent Surface-Aided Wireless Communications: Opportunities, Challenges, and Future Perspectives
Nhan Thanh Nguyen, Jiguang He, Van-Dinh Nguyen +5
Reconfigurable intelligent surfaces (RISs) have emerged as a cost- and energy-efficient technology that can customize and program the physical propagation environment by reflecting…
Machine Learning-Enabled Joint Antenna Selection and Precoding Design: From Offline Complexity to Online Performance
Thang X. Vu, Symeon Chatzinotas, Van-Dinh Nguyen +4
We investigate the performance of multi-user multiple-antenna downlink systems in which a BS serves multiple users via a shared wireless medium. In order to fully exploit the spati…
Energy Efficiency Maximization in RIS-Aided Cell-Free Network with Limited Backhaul
Quang Nhat Le, Van-Dinh Nguyen, Octavia A. Dobre +1
Integrating the reconfigurable intelligent surface in a cell-free (RIS-CF) network is an effective solution to improve the capacity and coverage of future wireless systems with low…
Learning-Assisted User Clustering in Cell-Free Massive MIMO-NOMA Networks
Quang Nhat Le, Van-Dinh Nguyen, Nam-Phong Nguyen +3
The superior spectral efficiency (SE) and user fairness feature of non-orthogonal multiple access (NOMA) systems are achieved by exploiting user clustering (UC) more efficiently. H…
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…
