The performance evaluation of a smart antenna receiver for WCDMA

This paper presents the performance of a smart antenna receiver for the uplink of a wideband code division multiple access (WCDMA) system in the frequency division duplex (FDD) mode. The beam-forming is implemented with a Lagrange multiplier based algorithm using Q channel. The results show that the smart antenna offers significant performance enhancement over a single antenna in a 3G environment (i.e.. with mixed traffic).
