CDMA 1xEVDO System with Smart Antenna Array

J. Castaneda-Camacho, M. Carro, D. Lara-Rodríguez, H. Azucena

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 direct-sequence 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.
