Abstract :
A new "geometrical model" of omnidirectional scatterers is proposed to derive rigorously explicit closed-form expressions for the joint/marginal probability density functions of the uplink/ downlink multipaths\´ time-of-arrival (TOA) and azimuth angle-of-arrival (AOA) in a wireless-communication fading-channel. The scatterers are herein spatially distributed in a multi-Gaussian model which is a weighted-sum of several uni-Gaussian model of scatterers\´ spatial density. By varying the weights and clusters location, this spatial density fits superior over existing models.
