CDMA 1xEVDO System with Smart Antenna Array

Abstract

Smart antennas have received increasing interest due to its capability for improving the performance of wireless radio systems. In this work we studied the throughput maximization in a CDMA 1xEV-DO cellular system when a smart antenna array is implemented. We focus in the downlink of the CDMA cellular system and consider a packet data directsequence code division multiple access (DS-CDMA). We show that it is possible to obtain a significant increment in the throughput of the system due to the switched beam smart antenna array.Keywords-Smart antenna, CDMA 1xEV-DO and CDMA throughput.
