The effect of power-control dynamics on the reverse-link capacity of a mobile CDMA cellular network

Abstract

The lack of a high-data-rate wireline backbone in a tactical CDMA cellular network limits the ability of the network to hand off mobile terminals rapidly between neighboring base stations. In previous work, it is shown that the limitation on handoff capability can have a severe impact on the reverse-link capacity of the network. The previous results employ an analysis of network capacity in which the multiple-access interference in each link is modeled as a stationary, Gaussian random process. In this paper, we employ a substantial refinement of the model in which we account for the dependence of the power-control dynamics of the multiple reverse links in the network. An evaluation is presented for the capacity of the network. The results are used to examine the effect of limited handoff capability on the network capacity.
