论文摘要
研究了可预测的接收器迁移率下智能反射表面（IRS）的运行。我们为多径通道开发了连续的时间系统模型，并讨论了有关收到的功率，多普勒传播和延迟差的最佳IRS配置。结果表明，无需将多普勒扩散添加到系统而可以最大化接收的功率。在一项数值案例研究中，我们表明，只有两个大型广告牌的IRS可以将地面与低地球轨道（LEO）卫星链路的链接预算提高高达6 dB。它还增加了第二个，几乎等效的沟通路径，从而提高了链接可靠性。
The operation of an intelligent reflecting surface (IRS) under predictable receiver mobility is investigated. We develop a continuous time system model for multipath channels and discuss the optimal IRS configuration with respect to received power, Doppler spread, and delay spread. It is shown that the received power can be maximized without adding Doppler spread to the system. In a numerical case study, we show that an IRS having the size of just two large billboards can improve the link budget of ground to Low Earth Orbit (LEO) satellite links by up to 6 dB. It also adds a second, almost equivalently strong, communication path that improves the link reliability.
