Abstract

This paper considers the increase in spectral efficiency of a TDMA PCS system employing smart antennas at the base station. Two different strategies are analyzed: spatial filtering for interference reduction (SFIR) and space division multiple access (SDMA). Our results indicate that a cluster size of N_cl=1 is possible by utilizing smart antennas. The use of SDMA increases the spectral efficiency over SFIR by 80%. Additionally, SDMA adds flexibility to the whole network
