全双工传输是一种很有前途的提高中继通信容量的技术。本文研究了全双工解码转发（DF）中继系统的最佳发射功率分配。以停电概率为优化准则，建立了有总功率约束和无总功率约束的系统发射功率优化问题。分析和数值结果表明了功率优化的优越性。更有趣的是，研究了全双工传输引入的剩余自干扰对优化功率分配和中断概率性能改善的影响。
Full duplex transmission is a promising technique to enhance the capacity of relay communications. In this paper, we investigate the optimum transmit power allocation for full duplex decode-and-forward (DF) relaying systems. The outage probability is adopted as the optimization criterion and a transmit power optimization problem is formulated for systems with and without total power constraint. Analytical and numerical results are provided to show the advantages of the power optimization. More interestingly, the effect of residual self-interference introduced by full duplex transmission is examined in terms of optimal power allocation and outage probability performance improvement.
