Abstract :
We propose a mathematical model to analyze call admission control schemes for a DS/CDMA cellular network. Although similar models have been proposed, they suffer some problems. The proposed model of this paper intends to correct them. In addition, we combine a modified linear programming technique to explore the issue of finding a better call admission control scheme for a DS/CDMA cellular network
