Over the last few years, wireless cellular communications has experienced rapid growth in the demand for provision of high data rate wireless multimedia services. This fact motivates the need to find ways to improve the spectrum efficiency of wireless communication systems. Smart or adaptive antennas have emerged as a promising technology to enhance the spectrum efficiency of present and future wireless communications systems by exploiting the spatial domain. This paper presents the analysis of base station adaptive antenna array performance in CDMA20001X mobile radio network. The results for the performance of CDMA20001x in the presence and absence of adaptive antenna array were simulated in Matlab. The simulation results show a significant reduction in the BER in the presence of adaptive antenna unlike in the absence of ad apti ve ant enna ar ray .

CDMA20001x is chosen as the platform for this paper since it has been adopted as the air-interface technology by the Third Generation (3G) wireless communication systems.
