摘要：

In this paper, we consider secure transmission for the full duplex relay network. Aiming to improve the physical layer security, we propose a full duplex hybrid relaying-andjamming (FDHRJ) scheme. In the FDHRJ scheme, we design a pre-coding matrix to form a jamming signal and let the relay simultaneously transmit both the desired signal and the jamming signal every slot. The destination can decode the desired signal and eliminate the jamming signal while the eavesdropper cannot do this. Based on the scheme, we derive an analytical expression of the system secrecy rate and the optimal power allocation between the desired signal and the jamming signal. The simulation results show that the proposed FDHRJ scheme with the optimal power allocation has better performance than the exiting schemes.
