摘　　要：对超宽带(UWB)室内信道模型在时域和频域进行了讨论,并介绍了在小范围衰落情况下的时域和频域的多种信道模型,以及较实用的路径损耗模型。根据测量结果分析了传统模型在视距(LOS)和非视距(NLOS) 情况下实测数据统计参数与模型参数的差异,并给出改进后的信道模型。最后讨论了超宽带信道建模所面临的困难和研究方向。In this paper,UWB indoor channcl models were discussed in time and frequency domain it＇s introduced path loss channels and several indoor channel models at small-scale fading.The difference between the measure parameters with the traditional model＇s paramctcrs in LOS and NLOS case is analyzed and the modified channel model is presented. The difficulties of channel modeling and the development trend are introduced in the end of this paper.
