Abstract
WCDMA networks are characterized by a single frequency reuse pattern along with the adaptation of
almost orthogonal CDMA coding scheme. Due to these facts the intra-system interference is considered
as the main limiting factor for the performance of WCDMA networks. Interference statistics determine
power consumption per user and thus sets network performance limits in terms of network capacity and
coverage.
The paper aims to develop a numerical statistical model that is going to perform power consumption
calculations on the downlink direction of WCDMA networks. Taking into account the stochastic
characteristics of power consumption along with several system settings the proposed model calculates
the average and the standard deviation value of downlink power consumption.The results obtained
from the above mentioned statistical model provide useful information that can be used in order to
interpret network performance under different radio propagation conditions and different system
settings.
