Modeling the Ultra-Wideband Outdoor Channel - Model Specification and Validation
Författare
Summary, in English
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.
