The use of adaptive antenna arrays in code division multiple access cellular communication system at base station is presented since the arrays have the ability to suppress the interference of multiple access and increase the capacity of the cellular system. The composition and adaptive algorithms of the arrays are studied. The performance of the proposed system is analyzed. Both theoretical analysis and numerical simulation results demonstrate that using the adaptive antenna arrays at base station
the performance of the system is improved and its capacity is increased comparing with those of the omnidirectional antenna system.
