Abstract :
In this paper, we proposed an analysis method on service capacity of CDMA system supporting data services. Cell spectrum efficiency and access available space the two concepts are used to constructed a new network performance evaluation system. An application layer service model and its corresponding cross-layer mapping method are also proposed. Based on the interference-limited CDMA system, we analysis the influence of different service characteristics for network performance both in single-service and multi-services condition.
