Abstract :
This paper presents the results from analysis of the forward link capacity for the third generation CDMA wireless system employing adaptive antenna arrays (AAA) at the base station. The capacity performance for mixed traffic scenarios of the forward link is studied in a multi-cell CDMA network including the array topology, multipath angle spread, and mean DOA beamforming technique. The effect of fast fading, log-normal shadowing, multiple access interference, and thermal noise is considered. The simulation results show that with the AAA, system capacity can be increased several fold compared to non-adaptive antenna base stations
