论文摘要
通过Landau的特征值定理提供了替代的自由度（DOF）公式（DOF）公式的替代推导。与其他方法相比，Landau的定理提供了一个通用框架来计算在任意环境中的DOF，此处是专门用于LOS传播的框架。该开发显示了该通道的空间限制性质与其在适用于大多数感兴趣的LOS设置的近似近似下的几何形状之间的关系。
An alternative derivation is provided for the degrees of freedom (DOF) formula on line-of-sight (LOS) channels via Landau's eigenvalue theorem for bandlimited signals. Compared to other approaches, Landau's theorem provides a general framework to compute the DOF in arbitrary environments, this framework is herein specialized to LOS propagation. The development shows how the spatially bandlimited nature of the channel relates to its geometry under the paraxial approximation that applies to most LOS settings of interest.
