Outage Analysis and Bilevel Resource Optimization in RIS-Assisted Clustered UAV-NOMA Networks
Masoud Ghazikor, Ly V. Nguyen, Morteza Hashemi
This paper investigates RIS-assisted downlink UAV communications based on NOMA. Since conventional NOMA becomes difficult to scale as the number of UAVs grows, we develop a cluster…
A Deep Reinforcement Learning Approach for Autonomous Reconfigurable Intelligent Surfaces
Hyuckjin Choi, Ly V. Nguyen, Junil Choi +1
A reconfigurable intelligent surface (RIS) is a prospective wireless technology that enhances wireless channel quality. An RIS is often equipped with passive array of elements and…
Joint Communications and Sensing Hybrid Beamforming Design via Deep Unfolding
Nhan Thanh Nguyen, Ly V. Nguyen, Nir Shlezinger +3
Joint communications and sensing (JCAS) is envisioned as a key feature in future wireless communications networks. In massive MIMO-JCAS systems, hybrid beamforming (HBF) is typical…
Variational Bayes Inference for Data Detection in Cell-Free Massive MIMO
Ly V. Nguyen, Hien Quoc Ngo, Le-Nam Tran +2
Cell-free massive MIMO is a promising technology for beyond-5G networks. Through the deployment of many cooperating access points (AP), the technology can significantly enhance use…
Variational Bayes for Joint Channel Estimation and Data Detection in Few-Bit Massive MIMO Systems
Ly V. Nguyen, A. Lee Swindlehurst, Duy H. N. Nguyen
Massive multiple-input multiple-output (MIMO) communications using low-resolution analog-to-digital converters (ADCs) is a promising technology for providing high spectral and ener…
