Outage performance of secure cooperative systems over correlated fading channels
摘要
Abstract
The outage performance of the secure cooperative system over correlated Rayleigh fading channels is investi-gated. Assuming that the transmitter knows the full channel state information before transmission, there exist one eaves-dropper and multiple cooperative relay nodes in system, and a relay node is chosen to act as jammer to send the jamming signals. Besides, in this cooperative system, the legitimate channel is correlated with the jamming channel to the destination, and the wiretap channel is correlated with the jamming channel to the eavesdropper. For this scenario, the expression of secrecy outage probability of the proposed secure cooperative system is derived. Numerical results show that the channel correlation has significant impacts on the secrecy performance of the secure cooperative system.关键词
