Abstract

WCDMA is becoming widely accepted as one of the most promising solutions to meet the increasing demand for high-capacity wireless networks of the future. The most important inherent characteristic of WCDMA systems is their interference-limited capacity. The user distribution is a very important issue. In most previous studies it is assumed that the spatial distribution of the users is uniform within the cell. This paper presents a study of the effect of a selected user distribution on the performance ofa WCDMA cellular system. A more realistic user distribution is chosen with specific parameters and a new interference distribution factor is developed as a function of these parameters. The capacity and coverage are compared for the uniform and nonuniform user distributions.
