A Frequency-Dependence Model for the Ultra-Wideband Channel based on Propagation Events

Abstract
While the frequency dependence of the wireless channel may be negligible for narrow to wideband signals, it has been shown that modeling this dependence for bandwidths in excess of 2 GHz improves channel reconstruction up to 40%.Yet to our knowledge, only Molisch et al. have done so for the ultra-wideband channel. Their benchmark frequency model however represents the average dependence over the collection of multi-path arrivals in the channel rather than that of individual arrivals. Building on the Geometric Theory of Diffraction, we propose a novel stochastic frequency model for individual arrivals according to the propagation events on their paths between the transmitter and receiver.Citation
