    In this paper, we analyze the performance of international mobile telecommunications (IMT) -2000 wideband code division multiple access (W-CDMA) smart antenna system with 5 MHz bandwidth in the reverse link. 9.6 Kbps traffic channel and dedicated pilot channel are included in our simulation. Dedicated pilot channel is used to both compensate channel error and estimate beamforming weight vector. Two-path Rayleigh fading and AWGN channels are considered. Simulation results are given in the form of average bit error rate (BER) vs. Eb/Io curve under various parameters including mobile speed, path-gain, and antenna number. On average, 3 dB Eb/Io gain increase is observed when four antenna elements are used compared with one antenna element for a fixed BER of 10^-3. Mobile speed effect on average BER is negligible because eight-element smart antenna system compensates for that.
