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…
Low-Latency and Secure Computation Offloading Assisted by Hybrid Relay-Reflecting Intelligent Surface
Khac-Hoang Ngo, Nhan Thanh Nguyen, Thinh Quang Dinh +2
Recently, the hybrid relay-reflecting intelligent surface (HRRIS) has been introduced as a spectral- and energy-efficient architecture to assist wireless communication systems. In…
Stochastic Geometry based Interference Analysis of Multiuser mmWave Networks with RIS
Joonas Kokkoniemi, Markku Juntti
In this paper, we utilize tools from stochastic geometry to estimate the interference propagation via reconfigurable intelligent surface (RIS) in the millimeter wave (mmWave, 30-30…
FPGA Implementation of Stair Matrix based Massive MIMO Detection
Shahriar Shahabuddin, Mahmoud A. Albreem, Mohammad Shahanewaz Shahabuddin +2
Approximate matrix inversion based methods is widely used for linear massive multiple-input multiple-output (MIMO) received symbol vector detection. Such detectors typically utiliz…
