摘要:The secrecy rate optimization of wireless communication systems with full-duplex (FD) relays and jamming signals is investigated in this work. Cooperated with FD relays, a novel secrecy transmission mechanism is proposed targeting at creating interference at eavesdroppers by adopting jamming signals. In the proposed mechanism, relays work in FD mode to receive information signals and forward them together with extra jamming signals. The global channel state information (CSI) is assumed available at all transmit nodes. Based on the proposed scheme, the secrecy rate of relay communication system is analyzed. Simulation results are also included to support the theoretical analysis. Results show that the proposed scheme can obviously enhance the secrecy rate of relay communication systems.
