Abstract

In this paper, we deal with the uplink outage probability for a UMTS cellular network at a reference base station equipped with a smart antenna. Users are assumed to be distributed according to a planar Poisson point process. Their respective transmission rates are modeled by independent random variables. This leads to a compound Poisson process for the total data rate to be served in a cell by code division multiplexing. Outage occurs if the total rate exceeds the effective chip rate (3.84 MChip/s divided by the minimum required bit energy to noise power ratio). Circulant matrices, a normal approximation, and Monte Carlo integration are employed to determine the outage probability as a performance parameter of the system.
