The use of space-time filtering is probably one of the most promising techniques for optimizing the utilization of the RF spectrum. Using an array of antennas at the base station, followed by a two-dimensional space-time filtering structure, a capacity improvement can be obtained by jointly reducing the co-channel and intersymbol interferences levels at the receiver. In this paper, simulations are made considering the GSM/GPRS system for different scenarios. The obtained results show that such a system can use not only all the frequencies in every cell, but also reuse a same carrier inside a single cell, employing spatial division multiple access (SDMA).
