Modeling the Ultra-Wideband Outdoor Channel - Model Specification and Validation

• 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.
