%X There had been astronomical increase in the number of mobile users in recent times. Investigation hadshown that these increased numbers of mobile users contribute high percentage of interferences thatdegrades the Quality of Services (QoS) in wireless network. Hence, interference is the most limitingfactor of improved capacity in CDMA cellular network and has been one of the problems militatingagainst the high efficiency of any mobile network. In effect, the scarcity of radio frequency spectrum andthe ever increasing network users has necessitated the need to adopt some channel assignment algorithmto achieve acceptable spectrum efficiency. This paper therefore analyses interferences in a CDMA-basedDCA algorithm with special emphasis placed on Adjacent Channel Interference (ACI) and Co-ChannelInterference (CCI). The CDMA system used in this study is Zoom, one of the leading mobile wirelessnetworks in South-East Nigeria. The developed models are simulated using Matlab. It was thereforediscovered that interferences have prominent roles to play in reliable channel assignment strategy andnetwork capacity in wireless system. Hence, in this paper, any reduction in interferences in cellularsystems translates into improving channel capacity of a wireless network.
