%X In order to decrease the total power expenditure under a promised QoS in Two-Way relay system,this paper proposed an optimal power allocation scheme based on minimizing total power expenditure.First derived the close form of outage probability in Two-Way relay system.Then established an optimal model to minimize the total power expenditure under the condition that the outage probability was a constant.Solved the optimal model by Lagrange multiplier method.Simultation result shows the proposed strategy can a...
