Abstract

We analyze the outage and capacity performance of an interference based admission control strategy in cellular CDMA systems. Most approaches to estimate the outage probability and the system capacity of CDMA systems in the literature do not take interference based admission control into account. In this paper, we present an analytical model to evaluate the outage probability and the capacity on the reverse link of cellular CDMA systems with interference based admission control. We make two main approximations in the outage analysis-one based on the central limit theorem (CLT) and the other based on the Chernoff bound (CB). We also obtain an improved approximation to the outage probability using Edgeworth expansion. It is shown that the considered admission control policy results in increased system capacity compared to that with no admission control, by about $30\%$ for an outage probability of 0.01.
