论文摘要
外部定位系统提供的位置信息，例如卫星导航，可以用作可重构智能表面（RIS）辅助表面（RIS）辅助表面（MMWave）多输入多输出多数输出网络的光束对齐和通道参数估计的先验信息。受益于此类先前信息的可用性，尽管不完美，但在所有端子上探索的候选梁较少，梁的比对和通道参数估计过程都可以显着加速。我们通过原子规范最小化提出了一种实用的通道参数估计方法，该方法的表现优于标准梁对准，以均方根误差和同一训练开销的有效频谱效率。
Location information offered by external positioning systems, e.g., satellite navigation, can be used as prior information in the process of beam alignment and channel parameter estimation for reconfigurable intelligent surface (RIS)-aided millimeter wave (mmWave) multiple-input multiple-output networks. Benefiting from the availability of such prior information, albeit imperfect, the beam alignment and channel parameter estimation processes can be significantly accelerated with less candidate beams explored at all the terminals. We propose a practical channel parameter estimation method via atomic norm minimization, which outperforms the standard beam alignment in terms of both the mean square error and the effective spectrum efficiency for the same training overhead.
