  Abstract

In this paper, we have analyzed mathematically the capacity of IMT-2000(WCDMA) reverse link with IC (Interference Canceller). Capacity is derived by the number of data service user(high speed) and voice service user(low speed) that have satisfied outage probability in multi-service environment considering the MAI(Multiple Access Interference) and Inter-cell interference. IMT-2000systems have utilized CDMA technique that has basis on the spread spectrum for the multiple access structure, so their capacity is very limited by the interference caused by data service users of inter and intra cell. But it is very difficult that we have calculated the interference accurately. In this paper, we proposed the model for the analysis of capacity at the multi service environment that using inter-cell interference to intra-cell interference ratio has the name of spillover ratio. This paper, we calculated the spillover ratio by a composition the service user at inter and intra cell, also presented the analysis model of capacity with outage probability as considering intra-cell and inter-cell interference. Using this capacity analysis model, we analyze the capacity and its gain with a canceller system that increases the system capacity by canceling the MAI or intra-cell interference. If we adapt canceller having 100% efficiency, we show the result that capacity gain factor is about 2 ~ 5 by each environment.
