论文摘要
在本文中，我们考虑了智能的Omni-Surfaces（IOSS），它们能够同时反射和折射电磁波。我们将注意力集中在多输入多出输出（MIMO）广播通道上，并引入了一种算法，用于共同优化基站的协方差矩阵，iOS的反射和变速箱系数的矩阵，以及对iOS进行了反射和重新划分的功率量。这项工作的可区分特征在于考虑到iOS的反射和传输系数紧密耦合。说明了仿真结果，以显示所提出的算法的收敛性以及同时反射和折射功能的表面的好处。
In this paper, we consider intelligent omni-surfaces (IOSs), which are capable of simultaneously reflecting and refracting electromagnetic waves. We focus our attention on the multiple-input multiple-output (MIMO) broadcast channel, and we introduce an algorithm for jointly optimizing the covariance matrix at the base station, the matrix of reflection and transmission coefficients at the IOS, and the amount of power that is reflected and refracted from the IOS. The distinguishable feature of this work lies in taking into account that the reflection and transmission coefficients of an IOS are tightly coupled. Simulation results are illustrated to show the convergence of the proposed algorithm and the benefits of using surfaces with simultaneous reflection and refraction capabilities.
