Abstract The 3G mobile communication system based on CDMA technique is expected to provide multi-services such as speech, video, email, FTP, Web browsing, etc. This paper presents a general analysis of the characteristics of the interference and capacity of the uplink of a multi-service cellular CDMA system. The system outage probability and capacity under different mixed traffic circumstances are analyzed respectively by approximating the interfer-ence with Gaussian and Lognormal distribution. The simulation results show the Lognormal approximation is more accurate than the Gaussian one. In addition, the impact of the shad-owing, power control error and imperfect sectorization on the interference and system capacity are evaluated.
