Full-duplex (FD) with simultaneous wireless information and power transfer (SWIPT) in wireless ad hoc networks has received increased attention as a technology for improving spectrum and energy efficiency. This paper studies the outage performance for a SWIPT-based decode-and-forward (DF) FD relaying network consisting of a single-antenna source S, a two-antenna relay R, and a multi-antenna destination D. Specifically, we propose four protocols, namely static time-switching factor with selection combining (STSF-SC), static time-switching factor with maximal ratio combining (STSF-MRC), optimal dynamic time-switching factor with selection combining (ODTSF-SC), and optimal dynamic time-switching factor with maximal ratio combining (ODTSF-MRC) to fully investigate the outage performance of the proposed system. In particular, the optimal time-switching factor from the ODTSF-SC and ODTSF-MRC methods is designed to maximize the total received data at the destination. In this context, we derive exact closed-formed expressions for all schemes in terms of the outage probability (OP). Finally, the Monte Carlo simulations are conducted to corroborate the theoretical analysis's correctness and the proposed schemes' effectiveness.
无线自组织网络中的全双工（FD）与同时无线信息和能量传输（SWIPT）作为一种提高频谱和能量效率的技术受到了越来越多的关注。本文研究了由单天线源S、双天线中继R和多天线目的地D组成的基于SWIPT的解码转发（DF）FD中继网络的中断性能。具体而言，我们提出了四种协议，即带选择合并的静态时间切换因子（STSF-SC）、带最大比合并的静态时间切换因子（STSF-MRC）、带选择合并的最优动态时间切换因子（ODTSF-SC）和带最大比合并的最优动态时间切换因子（ODTSF-MRC），以全面研究该系统的中断性能。特别地，ODTSF-SC和ODTSF-MRC方法的最优时间切换因子旨在最大化目的地接收到的总数据量。在此背景下，我们根据中断概率（OP）推导出所有方案的精确闭式表达式。最后，进行蒙特卡罗模拟以证实理论分析的正确性和所提方案的有效性。
