摘要/Abstract

摘要： 针对全双工解码转发中继网络中的安全传输问题,在最大传输功率和最小安全速率的限制下,提出一种功率分配策略,以提高安全速率。为解决优化过程中出现的非凸性问题,基于凸函数差规划和凸优化理论设计迭代算法。仿真结果表明,与传统的平均功率分配策略相比,该功率分配策略能够达到更高的安全速率。

关键词: 全双工中继, 功率分配, 凸优化, 迭代算法, 安全速率

Abstract: This paper investigates the security performance in the full-duplex relay network.Targeting on the improvement of the security performance,the power allocation is optimized with the consideration of the maximum transmit power and minimum security rate constraints.An efficient iterative algorithm based on DC programming and convex optimization is proposed to solve the nonconvex and difficult optimization problem.Simulation results verify the power allocation strategy proposed can achieve a higher security rate than the conventional average power allocation strategy.

Key words: full-duplex relay, power allocation, convex optimization, iterative algorithm, safety rate
