Abstract

In this paper, we propose a three-dimensional geometrically based stochastic model for the study of co-channel interference in cellular mobile systems. Exact analytical expressions for the statistics of the angle-of-arrival (AoA) of the interfering signals at the base station and the outage performance of a cellular network are derived. Simulated results show the merits of our proposal compared to the two-dimensional approach. The uplink AoA distribution statistics are examined in relation to cell size, antennas' height and frequency reuse factor. Furthermore, the impact of base station antenna radiation pattern, beam tilting and cell sectorization on system performance is investigated.
