In cellular systems, a code division multiple access (CDMA) technology with array antennas can significantly reduce interferences by taking advantage of the combination of spreading spectrum and spatial filtering. We investigate performance of cellular CDMA systems through adopting two types of array antennas, switched beam forming (SBF) and tracking beam forming (TBF) in the base station. Through Monte-Carlo simulations, we evaluate average bit-error-rate (BER) and outage probability of the systems under log-normal shadowing channels with multi-cell environment. When we consider 2 beams and 4 beams per sector for the SBF method, it is observed that the TBF method gives at least 10% and 30% capacity improvement over the SBF method in aspectsof 10^<-3> BER and 1% outage probability, respectively.
