摘要

我们报告了我们在办公大楼的几个场景中进行的超宽带(UWB)室内信道测量。给出了关于多径衰减的结果，支持了广泛假设的指数衰减在单簇情况下的适用性，并显示了由建筑内反射引起的双簇情况的一些结果。在幂律和多项式律的竞争中，详细讨论了信道增益随频率增加而发生的频率相关衰减。我们提出了走廊环境中接收功率与距离的幂律，最后提出了一些修改建议，以适应众所周知的传播模型元素。

Measurement results and modeling aspects for the UWB radio channel

We report on ultra-wideband (UWB) indoor channel measurements we have performed for several scenarios in an office building. Results are presented regarding the multipath decay supporting the applicability of the widely assumed exponential decay in a single cluster case, and show some results for a two-cluster situation caused by in-building back reflection. The frequency dependent decay of the channel gain with increasing frequencies is discussed in some detail regarding the competition between a power and a polynomial law. We present a power law for received power versus distance in a corridor environment and finally suggest some modifications allowing to adapt well known propagation model elements.
