论文摘要
全息图MIMO是一种具有空间约束的MIMO系统，具有大量天线，可能以最终形式将其视为空间连续的电磁孔。准确且可拖动的渠道建模对于理解该技术的全部潜力至关重要。本文考虑了任意的空间散射，并在笛卡尔坐标中提供了4D平面波的表示，该坐标捕获了电磁繁殖的本质，并允许评估具有矩形体积阵列的全息图MIMO系统的能力。开发的框架概括了虚拟通道表示，该表示最初是为均匀线性阵列开发的。
Holographic MIMO is a spatially-constrained MIMO system with a massive number of antennas, possibly thought of, in its ultimate form, as a spatially-continuous electromagnetic aperture. Accurate and tractable channel modeling is critical to understanding the full potential of this technology. This paper considers arbitrary spatially-stationary scattering and provides a 4D plane-wave representation in Cartesian coordinates, which captures the essence of electromagnetic propagation and allows to evaluate the capacity of Holographic MIMO systems with rectangular volumetric arrays. The developed framework generalizes the virtual channel representation, which was originally developed for uniform linear arrays.
