Abstract

Abstract: A physical-layer security enhancement scheme based on antenna selection and artificial noise (ASAN) was proposed. In broadcast phase, the Relay node selected the optimal antenna subset, and transmitted the beamforming matrix and artificial noise vector simultaneously. Simulation results show that the ASAN scheme outperforms classical beamforming scheme. Compared with beamforming scheme, the proposed scheme shows about 2.5dB gain in ergodic secrecy capacity when antenna number of Relay is three, and 3dB gain when the antenna number is six. Specifically, the combined selection criterion shows the similar curve compared with the one-direction criterion, in which the Relay only needs the channel information on Alice.
