Performance of smart antennas with adaptive combining at handsets for the 3GPP W-CDMA system

چکیده
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 = 5x10 and 5.5 dB for the GBSB circular model. The higher performance gain is achieved as the mobile velocity decreases.

In this paper, we propose a dual smart antenna system incorporated into handsets for the 3GPP WCDMA system, in which a diversity combiner combines the two rake receiver outputs using a diversity combining scheme. We considered three diversity combining schemes, selection diversity, square law combining, and equal gain combining (EGC), and two types of the channel model for the dual antenna sign...
