Abstract :
This paper presents the open literature\´s first marginal probability-density-functions of a UWB propagation system\´s uplink multipaths time-of-arrival (TOA) and azimuth direction-of-arrival (DOA), rigorously derived via thorough mathematics based on a "semi-geometrical" model of the two-dimensional (2D) spatial relationships among the user, the scatterers, and the base-station (BS). The spatial density of the scattered surrounding the user adopts the frequency-dependent received power distribution incorporating Gaussian distribution of scatterers around the user.
