Capacity allocation in multi-cell UMTS networks for different spreading factors with perfect and imperfect power control

An analytical model for calculating capacity in multi-cell UMTS networks is presented. Capacity is maximized for different spreading factors and for perfect and im-perfect power control. An analytical model is presented for approximating the user distributions in multi-cell third generationWCDMAnetworks using 2-dimensional Gaussian distributions by determining themeans and the standard deviations of the distributions for every cell. This allows for the calculation of the inter-cell interfer-ence and the reverse-link capacity of the network. The ca-pacity was determined for signal-to-interference thresh-old from 5 dB to 10 dB and spreading factor values of 256, 64, 16, and 4
