Sammanfattning

We discuss models for ultrawideband propagation channels. In contrast to conventional channels, a UWB channel extends over such a large bandwidth that the propagation conditions for the different frequency components can be markedly different. There is also a much better temporal resolution of multipath components, which leads to a breakdown of the usual assumption of Rayleigh fading. This paper presents an overview of existing models, discusses their strengths and weaknesses, and points out directions for future research in that area.
