论文摘要
车辆通信是第五代移动通信系统（5G）的重要应用。由于其成本较低和能源效率，智能反射表面（IRS）被设想为一种有前途的技术，可以通过被动边际形成可显着增强覆盖范围性能。在本文中，我们分析了IRS辅助的车辆通信网络中的中断概率性能。我们通过利用串联扩展和中心极限定理来得出中断概率的表达。数值结果表明，国税局可以显着降低其附近车辆的停战概率。中断概率与车辆密度和IRS元素的数量密切相关，并且具有更高的反射元素可以实现更好的性能。
Vehicular communication is an important application of the fifth generation of mobile communication systems (5G). Due to its low cost and energy efficiency, intelligent reflecting surface (IRS) has been envisioned as a promising technique that can enhance the coverage performance significantly by passive beamforming. In this paper, we analyze the outage probability performance in IRS-assisted vehicular communication networks. We derive the expression of outage probability by utilizing series expansion and central limit theorem. Numerical results show that the IRS can significantly reduce the outage probability for vehicles in its vicinity. The outage probability is closely related to the vehicle density and the number of IRS elements, and better performance is achieved with more reflecting elements.
