Abstract
This paper proposes the use of an adaptive array, which has the potential to reduce co-channel interference, for the base station, in order to increase the spectral efficiency without decreasing the cell radius. Computer simulation results show that the cluster size can be reduced to one, indicating that we can reuse the same frequency group at all cells. Furthermore, it is determined that wider element spacing provides better performance. The multipath model degrades the SIR performance in the down-link, the degradation being strongly dependent on inter-path correlation.<>
