Abstract :
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. For the full CSI of all link and the CSI for desired link, 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.
