Abstract :
In this paper the effects of adjacent channel interference on WCDMA capacity are studied for two adjacent frequency operators as well as for a hierarchical cell structure to be used by one operator at adjacent frequency channels. The effect of adjacent channel interference on the system capacity is studied with practical loading of the WCDMA system. Also a new model for adjacent channel interference in the uplink is introduced taking into account the behaviour of a practical WCDMA terminal power amplifier. A goal of this paper is to find out the adjacent channel interference requirements for the WCDMA system
