Abstract

The IMT-2000 standard UMTS of (Universal Mobile Telecommunications System) is based on Wideband CDMA (Code Division Multiple Access). To access a shared transmission channel for multiple users, UMTS exploit Code Division Multiple Access (CDMA). Multi-user interference is a critical issue in CDMA, limited user, cell Capacity and limiting spectral efficiency dramatically. The manner of used multiple carriers can provide capacity increases over and above a simple doubling of capacity. Models involving power, signaling and cell size design will be developed to determine the best configuration for improved capacity within the UMTS/3G network. This paper will explain the analytical calculation of Multi-Frequency scenario within UMTS/3G for user capacity enhancement with number of services in cells of clusters.
