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.
