全双工传输是一种很有前途的提高中继通信容量的技术。在本文中,我们研究全双工解码转发(DF)中继系统的功率和位置优化。采用中断概率作为优化准则,并制定了一个二维(2D)的优化问题,系统有和没有直接的源-目的地链路。分析和数值计算结果证明了功率和位置优化的优点。更有趣的是,残余自干扰(RSI)全双工传输引入的最佳功率分配和中继位置部署和中断概率性能的改善方面的影响进行了研究。此外,我们表明,最小的中断概率可以通过联合电源位置优化。功率优化的中断性能的影响也比较全双工和半双工中继。
Full-duplex transmission is a promising technique to enhance the capacity of relay communications. In this paper, we investigate the power and location optimization for full-duplex decode-and-forward (DF) relaying systems. The outage probability is adopted as the optimization criterion and a two-dimensional (2D) optimization problem is formulated for systems with and without the direct source-destination link. Analytical and numerical results are provided to demonstrate advantages of the power and location optimization. More interestingly, the effect of residual self-interference (RSI) introduced by full-duplex transmission is investigated in terms of the optimal power allocation and relay location deployment and the outage probability performance improvement. Furthermore, we show that the minimal outage probability can be achieved via joint power-location optimization. The effect of power optimization on the outage performance is also compared between full-duplex and half-duplex relaying.
