摘要：In this paper, we investigate the secrecy outage probability (SOP) for the cooperative amplify-and-forward (AF) two-way relay networks (TWRN) with channel estimation (CE) errors under Rayleigh fading channels. In the proposed system, two sources simultaneously broadcast their respective information to all the relays firstly. Then, the optimal relay performs AF protocol on the received signals sent from the two sources and forward them to both sources. In both phases, An eavesdropper receives the signals from sources and relay nodes illegally. The performance of the proposed system is quantified by deriving the upper bound of the overall outage probability. Impact of CEs on the system is illustrated by simulations.
