UWB Fading Characteristics in a Typical Office Environment

摘要

This paper investigates the slow- and fastfadingcharacteristics of an ultra-wideband (UWB)pulse transmission in a typical office environment.924 impulse responses were recorded in 24 locationsover a single floor and analyzed according to pathtopography. The standard deviation of the slowfadingwas empirically determined to be less than2.68 dB for all topographies. The fast-fadingcharacteristics were also investigated to capture theless predictable scattering behavior of theenvironment. Results show that the complexscattering amplitudes of the elemental scatterers areuncorrelated for all topographies. We conclude thatthe UWB channel can be modeled as a WSSUSchannel.
