Abstract :
This paper deals with a novel balancing method for the carrier to interference ratio C/I in the downlink of a digital cellular radio system, using an array antenna in conjunction with beam forming techniques at the base stations. This concept 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 C/I are determined in order to evaluate the performance improvements enabled by the novel balancing method
