Abstract

Abstract In recent years, the development of intelligent reflecting surface (IRS) in wireless communications has enabled control of radio waves to reduce the detrimental impacts of natural wireless propagation. These can achieve significant spectrum and energy efficiency in wireless networks. Non-orthogonal multiple access (NOMA) technology, on the other hand, is predicted to improve the spectrum efficiency of fifth-generation and later wireless networks. Motivated by this reality, we consider the IRS-based NOMA network in the downlink and uplink scenario with a pernicious eavesdropper. Moreover, we investigated the physical layer security (PLS) of the proposed system by invoking the connection outage probability (COP), secrecy outage probability (SOP), and average secrecy rate (ASR) with analytical derivations. The simulation results reveal that (i) it is carried out to validate the analytical formulas, (ii) the number of meta-surfaces in IRS, transmit power at the base station, and power allocation parameters all play an essential role in improving the system performance, and (iii) it demonstrates the superiority of NOMA to the traditional orthogonal multiple access (OMA).

基于irs的下行和上行NOMA网络物理层安全性分析

近年来，智能反射面(IRS)技术在无线通信领域的发展，使无线电波的控制能够减少自然无线传播的不利影响。这些可以在无线网络中实现显著的频谱和能源效率。另一方面，预计非正交多址(NOMA)技术将提高第五代及以后无线网络的频谱效率。基于这一现实，我们考虑了具有恶意窃听者的基于irs的NOMA网络下行和上行场景。此外，我们还通过调用连接中断概率(COP)、保密中断概率(SOP)和平均保密率(ASR)对所提出系统的物理层安全性(PLS)进行了分析推导。仿真结果表明:(1)分析公式的正确性得到了验证;(2)IRS元曲面数、基站发射功率和功率分配参数对系统性能的提高都起着至关重要的作用;(3)NOMA相对于传统的正交多址(OMA)具有优越性。

期刊介绍： The overall aim of the EURASIP Journal on Wireless Communications and Networking (EURASIP JWCN) is to bring together science and applications of wireless communications and networking technologies with emphasis on signal processing techniques and tools. It is directed at both practicing engineers and academic researchers. EURASIP Journal on Wireless Communications and Networking will highlight the continued growth and new challenges in wireless technology, for both application development and basic research. Articles should emphasize original results relating to the theory and/or applications of wireless communications and networking. Review articles, especially those emphasizing multidisciplinary views of communications and networking, are also welcome. EURASIP Journal on Wireless Communications and Networking employs a paperless, electronic submission and evaluation system to promote a rapid turnaround in the peer-review process. The journal is an Open Access journal since 2004.
