Capacity and coverage in mixed traffic UMTS CDMA systems

This paper examines the related issues of capacity, coverage and power control in a multi-cell WCDMA network. The analysis is presented for the forward link. The analysis is based on extended models used for IS-95 systems which rely on Gaussian assumptions of interference. The analytical models presented and evaluated give an insight into the effects of varying traffic types, different allowances for signal to interference ratio (SIR) targets and mixed traffic.
