Multipath propagation model for High Altitude Platform (HAP) based on circular straight cone geometry

A geometric model that describes a multipath propagation for a fixed wireless communication system between a high altitude platform and a fixed terrestrial user is presented. The model describes the propagation of the reflected signals that are able to reach the receiver as a consequence of all the scatterers located inside the system coverage area. The establishment of a particular geometry characterizing the system coverage area allows the behavior of the multipath phenomenon effects to be modeled accurately.
