Abstract

In this paper, a method for adaptive cooperation of base stations in cellular systems is presented and its performance is analyzed theoretically. The base station cooperation is selected based on SINR value for a mobile station: if the SINR value is less than a given threshold, then the base station cooperation is carried out, else the base stations communicate with mobile stations independently. Performance of cellular systems has been done by computer simulation, which needs a big software development and a long simulation time. In this paper theoretical analysis of the performance is made under the path-loss, the shadowing and the Rayleigh fading and inter-cell interference. Formula for distribution function of S(I)NR is obtained. By numerical calculation of the distribution of S(I)NR, cell average and cell edge (5%) throughput are given. It is sown that cell edge throughput can be highly increased without significant loss of the average throughput with the adaptive base station cooperation.
