A 3D Spatial Channel Model for Cellular Radio

Abstract

This thesis provides closed form expressions for the angular distribution in azimuth and elevation planes for a geometrically based single bounce spheroid model, The geometry of the spheroid is defined by the semi-major axis a and the semi-minor axis b. The other parameter of interest in the model is the distance D between the base station and the mobile station. The latter is assumed to be at the center of the spheroid. The mobile station is assumed to be the transmitter, while the base station is the receiver. This thesis investigates the effects of the above parameters on the angular distribution of the received waves. Important parameters such as the r.m.s angle spread in azimuth and elevation plane are calculated from the p.d.f. expressions derived. The behavior of these r.m.s angle spreads versus the ratio a/D or b/D respectively is also investigated.
