摘要：
In this paper, an energy-efficient power allocation problem is studied for a secure full-duplex (FD) relay network. The problem is formulated as a nonconvex optimization program to achieve the maximum of secure energy efficiency with power constraints and a preset secure quality-of-service (QoS). By analyzing the structure of the objective function, we found that the problem can be solved by leveraging DC-based optimization and fractional programming. As a result, a successively convex approximation algorithm is proposed for handling the nonconvex problem. Numerical results validate the effectiveness of the proposed scheme.
