Uplink capacity studies for adaptive antenna arrays in third generation CDMA wireless systems

The effects of using adaptive antenna arrays in third generation CDMA wireless systems are analyzed through simulation studies. The capacity performance in multi-rate traffic scenarios of the reverse link is examined under various vector channel models and user population mixtures, along with comparisons with switched beam systems. The results indicate that adaptive antenna arrays have a clear advantage in mixed rate traffic in comparison to non-adaptive antenna techniques, while their performance is highly sensitive to channel conditions and the array topology.
