摘要：
In this paper, we propose an optimal source power allocation scheme for a two-hop amplify-and-forward relaying network with cooperative jamming where a source and destination transmit jamming signals. When the full CSI of all links are available and when only the CSI for desired links are available, the source power is optimally splitted to minimize the secrecy outage probability. Simulation results show that the proposed power allocation scheme improves the secrecy rate and reliability.
