PERFORMANCE GAIN OF SMART DUAL ANTENNAS AT HANDSETS IN 3G CDMA SYSTEM

In this paper, we present simulation results for the performance gain of smart dual antennas at handsets for the forward link in the cdma2000 system. The system was modeled with the SPW of Cadence. Three types of the channel model, two levels of diversity combining, and three diversity combining schemes were investigated. Our simulation results show that the average performance gain (reduction of the frame error rate) of a smart dual antenna system lies in the range of 1.7 dB to 12.7 dB depending on the correlation of the dual antenna signals.
