摘要

利用网络分析仪对住宅传播环境下UWB (2- 8ghz)信道的空间依赖性进行了测量。测量表明，空间相关长度范围从约2至6英寸的LOS和NLOS几何。到达角分布显示出明显的频率相关散射射线和较强的窄角散射能量成分。LOS的联系似乎被限制在10度左右。对于NLOS链路，到达角分布更宽。

Spatial correlation of UWB signals in a home environment

Measurements of the spatial dependence of UWB (2-8 GHz) channels were made for a residential propagation environment using a network analyzer. Measurements indicate spatial correlation lengths ranging from about 2 to 6 inches for both LOS and NLOS geometries. The angle-of-arrival distribution showed discernible frequency-dependent rays of scattered energy and a strong component of narrow angle scatter energy. The LOS link appeared to be limited to about 10 degrees. For the NLOS link the angle-of-arrival distribution was wider.
