This paper presents an analysis of the CDMA uplink capacity with smart antennas. Traditionally, the capacity of a system is determined by outage probability. In our analysis, we introduce a transient capacity analysis based on the on-off traffic model for multi-cell CDMA networks with smart antennas at the base station. For real-time connection admission control (CAC) applications, we derive the transient outage probability as the quality of service (QoS) measure using the fluid-flow model and central limit approximation. Based on the outage measures, we compare the transient outage performance with the steady state outage performance. Numerical results show that predictive CAC is a promising approach for multi-cell CDMA networks.
