论文摘要
本文调查了非正交多访问（NOMA）在阴影褪色渠道上应用于卫星通信网络。从实际情况的角度考虑了不完善的连续干扰取消（IPSIC）对基于NOMA的卫星网络的影响。我们首先为p-th陆地用户提供了新的断电概率表达式，并提供相应的渐近分析结果。零和P的多样性顺序分别由IPSIC和完美连续的干扰取消（PSIC）实现。最后，提出的仿真结果表明：1）在PSIC的条件下，基于NOMA的卫星网络的中断行为优于正交多重访问； 2）随着剩余干扰的价值增加，具有iPSIC的陆地用户的中断性能变得更加严重； 3）与频繁的沉重和平均阴影相比，阴影褪色的光阴影淡阴影带来了更好的中断概率。
This paper investigates the application of non-orthogonal multiple access (NOMA) to satellite communication network over Shadowed-Rician fading channels. The impact of imperfect successive interference cancellation (ipSIC) on NOMA-based satellite network is taken into consideration from the perspective of practical scenarios. We first derive new exact expressions of outage probability for the p-th terrestrial user and provide the corresponding asymptotic analysis results. The diversity order of zero and p are achieved by the p-th terrestrial user with ipSIC and perfect successive interference cancellation (pSIC), respectively. Finally, the presented simulation results show that: 1) On the condition of pSIC, the outage behaviors of NOMA-based satellite network are superior to that of orthogonal multiple access; 2) With the value of residual interference increasing, the outage performance of terrestrial users with ipSIC is becoming worse seriously; and 3) Infrequent light shadowing of Shadowed-Rician fading brings the better outage probability compared to frequent heavy and average shadowing.
