论文摘要
在本文中，基于多个多元访问的合作继电器系统（NOMA-CRS）被认为可提高光谱效率。此外，还为Noma-CR中的继电器提出了同时的无线信息和电力传输（SWIPT）。在Swipt-Noma-CR中，实施了三种不同的能源收集（EH）协议，功率共享（PS），时间共享（TS）和理想协议。研究了所有三种EH方案的SWIPT-NOMA-CRS的中断性能。在分析中，为了代表实际/合理的方案，考虑了不完善的连续干扰取消器（SIC）和不完美的通道状态信息（CSI）。派生的中断概率（OP）表达式通过计算机模拟验证。此外，在不完美的SIC和CSI下也得出了基准方案的OP NOMA-CRS。基于广泛的模拟，据显示，swipt-noma-crs的表现优于没有EH的Noma-Crs。最后，讨论了所有参数对Swipt-noma-Crs中断性能的影响，并且在给定的情况下，展示了最佳PS因子，TS因子和功率分配系数。
In this paper, a non-orthogonal multiple access based cooperative relaying system (NOMA-CRS) is considered to increase spectral efficiency. Besides, the simultaneous wireless information and power transfer (SWIPT) is proposed for the relay in NOMA-CRS. In SWIPT-NOMA-CRS, three different energy harvesting (EH) protocols, power sharing (PS), time sharing (TS) and ideal protocols are implemented. The outage performances of the SWIPT-NOMA-CRS are studied for all three EH protocols. In the analysis, to represent practical/reasonable scenarios, imperfect successive interference canceler (SIC) and imperfect channel state information (CSI) are taken into consideration. The derived outage probability (OP) expressions are validated via computer simulations. Besides, the OP for the benchmark scheme, NOMA-CRS without EH, is also derived under imperfect SIC and CSI. Based on extensive simulations, it is revealed that the SWIPT-NOMA-CRS outperforms NOMA-CRS without EH. Finally, the effects of all parameters on the outage performance of the SWIPT-NOMA-CRS are discussed and for the given scenarios, the optimum PS factor, TS factor and power allocation coefficients are demonstrated.
