In this Letter, performance of multiple users in downlink of non-orthogonal multiple access (NOMA) network considering the general α − κ − μ shadowed fading model which was proposed in recent years is studied. In particular, main metrics including the outage probability, ergodic rate related to ordered channels are derived in novel and exact expressions for arbitrary values of the fading parameters. Moreover, numerical simulations are carried out in order to exhibit further insights on how the system performance is affected by the fading parameters.

多用户 NOMA 在 $\alpha-\kappa-\mu$ Shadowed Fading 上的性能分析

在这封信中，考虑了近年来提出的通用α-κ-μ阴影衰落模型，研究了非正交多址（NOMA）网络下行链路中多用户的性能。特别是，包括中断概率、与有序信道相关的遍历速率在内的主要指标以衰落参数的任意值的新颖且精确的表达式导出。此外，还进行了数值模拟，以进一步了解衰落参数如何影响系统性能。
