摘要:

在本文中,我们介绍了一个理论框架,分析性能的多可重构智能表面(RIS)授权太赫兹(THz)无线系统受到湍流和随机光束失调。更详细地说,我们提取了一个封闭形式的表达式的中断概率,量化的湍流和未对准的联合影响,以及收发器的硬件缺陷的影响。我们的研究结果强调了在评估多RIS授权的THz无线系统的性能时准确建模湍流和未对准的重要性。

英文摘要:

In this paper, we introduce a theoretical framework for analyzing the performance of multi-reconfigurable intelligence surface (RIS) empowered terahertz (THz) wireless systems subject to turbulence and stochastic beam misalignment. In more detail, we extract a closed-form expression for the outage probability that quantifies the joint impact of turbulence and misalignment as well as the effect of transceivers' hardware imperfections. Our results highlight the importance of accurately modeling both turbulence and misalignment when assessing the performance of multi-RIS-empowered THz wireless systems.
