Achievable Rate of a STAR-RIS Assisted Massive MIMO System Under Spatially-Correlated Channels
Anastasios Papazafeiropoulos, Le-Nam Tran, Zaid Abdullah +2
Reconfigurable intelligent surfaces (RIS)-assisted massive multiple-input multiple-output (mMIMO) is a promising technology for applications in next-generation networks. However, r…
SCA-Based Beamforming Optimization for IRS-Enabled Secure Integrated Sensing and Communication
Vaibhav Kumar, Marwa Chafii, A. Lee Swindlehurst +2
Integrated sensing and communication (ISAC) is expected to be offered as a fundamental service in the upcoming sixth-generation (6G) communications standard. However, due to the ex…
Optimization of RIS-aided SISO Systems Based on a Mutually Coupled Loaded Wire Dipole Model
Nemanja Stefan Perović, Le-Nam Tran, Marco Di Renzo +1
The electromagnetic (EM) features of reconfigurable intelligent surfaces (RISs) fundamentally determine their operating principles and performance. Motivated by these consideration…
A Low-Complexity Solution to Sum Rate Maximization for IRS-assisted SWIPT-MIMO Broadcasting
Vaibhav Kumar, Anastasios Papazafeiropoulos, Muhammad Fainan Hanif +2
This paper focuses on the fundamental problem of maximizing the achievable weighted sum rate (WSR) at information receivers (IRs) in an intelligent reflecting surface (IRS) assiste…
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…
