PERFORMANCE OF SMART ANTENNAS WITH ADAPTIVE COMBINING AT HANDSETS FOR THE cdma2000 SYSTEM

In this paper, we present simulation results for the performance gain of smart dual antennas with adaptive combining at handsets for the forward link in the cdma2000 system. The adaptive algorithm based on the normalized least-mean-square (N-LMS) algorithm is applied, in which antenna weights are recursively obtained. The system was modeled with the SPW of Cadence. Our simulation results show that the performance gain (in terms of the reduction of the frame error rate) of a smart dual antenna system over a single antenna system lies in the range of 0.8 dB to 2.2 dB depending on the mobile velocity.
