Abstract

The analysis of outage performance in a Non-Orthogonal Multiple Access (NOMA) based network is conducted for a hybrid model that combines an IRS with a decode-forward relay. The use of an IRS-assisted relay network is particularly significant in environments with deep fading. The outage performance of each user in different ordered NOMA configurations has been evaluated, taking into account different numbers of IRS elements. The optimal number of users that can be accommodated by a source using NOMA for a specific threshold has been identified. The required number of active reflecting elements has been estimated to achieve a target SINR for a given order of NOMA. Additionally, a closed-form expression and its asymptotic expressions have also been derived for the outage probability of all users. The analytical results have been validated via Monte Carlo simulations.

irs辅助中继NOMA网络的中断分析
针对一种将IRS与译码转发中继相结合的混合模型,对基于非正交多址(NOMA)的网络中断性能进行了分析。irs辅助中继网络的使用在深度衰落的环境中尤为重要。考虑到不同数量的IRS元素,对不同有序NOMA配置下每个用户的停机性能进行了评估。对于特定阈值,已经确定了使用NOMA的源可以容纳的最佳用户数量。为达到给定阶数的NOMA的目标SINR,估计了所需的有源反射元件数量。此外,还导出了所有用户的停电概率的封闭表达式及其渐近表达式。通过蒙特卡罗模拟验证了分析结果。
