Secrecy Capacity Maximization for a Hybrid Relay-RIS Scheme in mmWave MIMO Networks
Edson Nobuyuki Egashira, Diana Pamela Moya Osorio, Nhan Thanh Nguyen +1
The hybrid relay-reflecting intelligent surface (HR-RIS) has been recently introduced as an efficient solution to overcome the double path loss and limited beamforming diversity of…
Coordinated Pilot Transmissions for Detecting the Signal Sparsity Level in a Massive IoT Network under Rayleigh Fading
Onel L. A. López, Glauber Brante, Richard D. Souza +2
Grant-free protocols exploiting compressed sensing (CS) multi-user detection (MUD) are appealing for solving the random access problem in massive machine-type communications (mMTC)…
Hybrid Active-Passive Reconfigurable Intelligent Surface-Assisted Multi-User MISO Systems
Nhan Thanh Nguyen, Van-Dinh Nguyen, Qingqing Wu +3
We consider a multi-user multiple-input single-output (MISO) communications system which is assisted by a hybrid active-passive reconfigurable intelligent surface (RIS). Unlike con…
