Secret Channel Training to Enhance Physical Layer Security With a Full-Duplex Receiver

Yan, Shihao; Yang, Nan; Abhayapala, Thushara; Swindlehurst, A. Lee; Zhou, Xiangyun


This work proposes a new channel training (CT) scheme for a full-duplex receiver to enhance physical layer security. Equipped with NB full-duplex antennas, the receiver simultaneously receives the information signal and transmits artificial noise (AN). In order to reduce the non-cancellable self-interference due to the transmitted AN, the receiver has to estimate the self-interference channel prior to the data communication phase. In the proposed CT scheme, the receiver transmits a...[Show more]
