Abstract :
In this paper, we have reported on the BER and outage analysis of a smart antenna system for reverse link of IS-95 CDMA. We have defined new figures of merit for smart antennas (smart antenna gain and outage probability). Simulation results have been presented showing how these figures of merit, and additionally the mean BER, vary with the number of antennas (N) and number of users under different channel conditions. It has been found that significant improvement in outage occurs in the range 1 /spl les/ N /spl les/ 4. When N increases from 4 to 8, the outage probability reduction is not significant, especially for pedestrian channels. This observation is of value in the planning of smart antenna structures for urban areas. The reported results assume perfect adaptation.
