An efficient multipath channel model for UWB home networking

In this paper, we extend our previous work in [1-3] to conduct the time-domain transmitted field through a lossy dielectric slab so that our time-domain UWB multipath propagation channel model can characterize the most important electromagnetic wave propagation mechanisms' such as reflection, diffraction, and transmission, in a home environment. In order to effectively determine the UWB transmitted field through the lossy material, a time-domain transmission coefficient is derived in a closed form. The analytical solution includes both perpendicular polarization and parallel polarization. Simulation results which take into account all possible rays in a typical UWB home environment are presented and some guidance for the UWB home networking is presented.
