Abstract

This paper presents an large deviation theory approach 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 On-Off traffic model for multi-cell CDMA systems with smart antennas at the base station. We derive the transient outage probability as the quality of service (QoS) measure using the fluid-flow model, central limit approximation, and chernoff bound. Based on the outage measures, we compare transient outage performance against steady-state outage performance. Numerical results show that the predictive (transient) CAC is a promising approach for the multi-cell network.
