论文摘要
可重新配置的智能表面（RIS）是一种采用元图来反映从源节点到目标节点的信号的新兴技术。通过巧妙地重新配置元图的电磁（EM）特性并调整反射无线电波的EM参数，RIS可以将无法控制的繁殖环境转变为可达的可重新配置空间，因此可以显着提高通信能力并改善系统的覆盖范围。在本文中，我们研究了远场通道，其中视线（LOS）传播是主导的。我们提出了一个天线模型，该模型可以表征逼真的RIS元件的辐射模式，并考虑从RIS的两跳路径接收到的信号功率。在各种场景和参数下对网络性能的系统级模拟。
Reconfigurable intelligent surface (RIS) is an emerging technique employing metasurface to reflect the signal from the source node to the destination node. By smartly reconfiguring the electromagnetic (EM) properties of the metasurface and adjusting the EM parameters of the reflected radio waves, RIS can turn the uncontrollable propagation environment into an artificially reconfigurable space, and thus, can significantly increase the communications capacity and improve the coverage of the system. In this paper, we investigate the far field channel in which the line-of-sight (LOS) propagation is dominant. We propose an antenna model that can characterize the radiation patterns of realistic RIS elements, and consider the signal power received from the two-hop path through RIS. System-level simulations of network performance under various scenarios and parameter.
