Abstract

This paper analyzes the influence of the geometrical distribution of mobile users on a novel balancing method for the carrier (C) to interference (I) ratio γ in the downlink of a digital cellular radio system. The C/I balancing concept, which uses an array antenna in conjunction with beam forming techniques at the base stations, is an extension of the well-known centralized power control scheme for single antenna systems. Based on Monte Carlo simulations of a cellular environment, cumulative distribution functions of γ are determined in order to find out if performance improvements can be obtained by identifying and taking out mobile users which cause especially large contributions to the total interference
