论文摘要
在这封信中，我们考虑了带有矩形对称性的空间约束天线孔的收发器，并旨在改善空间自由度（DOF）和通道容量利用evanescent的能力，从而根据傅立叶平面系列扩展，以在近场场景中进行信息传递。该处理仅限于各向同性散射环境，但可以通过平面波传播的线性系统理论解释将其扩展到非各向同性情况。数值结果表明，衰落的波具有在近场区域提供额外的DOF和容量的重要潜力。
In this letter, we consider transceivers with spatially-constrained antenna apertures of rectangular symmetry, and aim to improve of spatial degrees of freedom (DoF) and channel capacity leveraging evanescent waves for information transmission in near-field scenarios based on the Fourier plane-wave series expansion. The treatment is limited to an isotropic scattering environment but can be extended to the non-isotropic case through the linear-system theoretic interpretation of plane-wave propagation. Numerical results show that evanescent waves have the significant potential to provide additional DoF and capacity in the near-field region.
