Physical layer security of NOMA-D2D cooperative wireless system

Dianxin kexue, 2022
Aiming at the physical layer security (PLS) application requirement of massive user equipments access in the future, the PLS model combining with non-orthogonal multiple access (NOMA), device-to-device (D2D) and relay cooperation was proposed.The model ...

Multi-Eavesdropper Detection Through PHY-Aware Cell-Free AP Selection

IEEE Access
The ability to provide reliable data rates across several coverage areas establishes massive multiple-input multiple-output (m-MIMO) cell-free (CF) systems as a pivotal technology for future sixth-generation (6G) systems.

Secrecy Capacity and Efficiency Outage Analysis of Cooperative PHY-Secure Wireless Systems and Secrecy Capacity-Based RIS Design

IEEE Access
Physical layer (PHY) security (PLS) leverages the inherent randomness of wireless fading channels to provide enhanced secrecy capacity. In this work, we consider a four-node, dual hop, eavesdropper-aware cooperative PHY-security model.
