Minimum duration outage analysis of cellular CDMA for integrated services with correlated signal and interference

Abstract

Minimum duration outage analysis has been carried out for a cellular system supporting both voice and data services. The outage has been defined as the excursion of SIR (signal-to-interference ratio) below a threshold level for a certain minimum duration. A mathematical formulation with closed form expression for minimum duration outage considering the correlation between the signal and interference is presented. The capacity of the system in terms of the number of users is related to minimum duration outage probability considering an appropriate interference model.
