Sammanfattning

In this paper we establish a geometry-based stochastic

ultra-wideband channel model for outdoor infostations scenarios.

We statistically describe the

location and strength of clusters of scatterers, as well as the shape and width of

visibility and shadowing regions. We also separately model diffuse

radiation (which cannot be explained by the scatterer components),

and show that its fading statistics can be best described by a

Weibull distribution with a delay dependent beta-parameter. A step-by-step implementation

recipe demonstrates that the overall model can be implemented with little

programming effort. Finally, we validate our model comparing with secondary channel parameters

as rms delay spread, and show that the model can accurately describe the measured channel properties

having a general applicability for these class of scenarios.
