Beamforming and jamming for physical-layer security with different trust degrees
CDT Thai - AEU-International Journal of Electronics and …, 2021 - Elsevier
In this paper, a network with multiple-antenna legitimate nodes and single-antenna
illegitimate nodes (INs) with different trust degrees (TD), such as trusted cooperative,
untrusted cooperative, non-cooperative, and eavesdropping nodes, is considered. I propose
a novel scheme for beamforming and jamming to improve the secrecy rate (SR). Simulation
results show that its SR is higher than that of conventional schemes without exploiting the
TD information and/or without such beamforming and jamming design.
