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 frequency model for individual arrivals according to the propagation events on their paths between the transmitter and receiver.Conference Title
