Abstract

Time-scale domain geometrical-based method for the characterization of the time varying infostation ultrawideband (UWB) channel is presented. This model arises primarily from the integration of geometrical, electromagnetic and statistical assumptions from a physical propagation point of view to account for frequency dependent path-loss, frequency/time dispersion in the UWB channel. Results show that the frequency dispersion of the channel depends on the frequency and not on the choice of bandwidth. And time dispersion depends on bandwidth and not on the frequency.
