We present the performance gain of dual smart antennas with an adaptive combining at handsets for the 3GPP WCDMA system. The adaptive algorithm based on the normalized least-mean-square (N-LMS) algorithm is employed, in which antenna weights are recursively obtained. To obtain the channel profile, we adopted the GBSB (geometrically based single bounce) elliptical and circular models. The simulation results show that the dual smart antenna system with the adaptive combining performs better than a single antenna system and its performance gain is 3.3 dB for the GBSB elliptical model at BER = 5×10-2 and 5.5 dB for the GBSB circular model. The higher performance gain is achieved as the mobile velocity decreases.
