Abstract

In this paper, we investigate the performance of the W-CDMA system with smart antenna. A realistic wideband channel is assumed, one of which is ITU-R M1225 channel model. It is also assumed that the multipaths are clustered. The beamforming-RAKE receiver structure of the W-CDMA system is proposed, whose performance is analyzed on the assumption of perfect channel estimation. The probability density function (pdf) of SINR (signal-to-interference-plus-noise ratio) for different numbers of antennas and users is presented and the BER (bit error rate) is presented based on that. As a result, the performance of the W-CDMA system with smart antenna in the realistic wideband channel has been considerably improved
