Abstract Power control is an effective approach to overcome "near-far" problem, reduce intercell interference and increase system capacity in code division multiple access (CDMA) mobile communication systems. At the same time, power control can provide different quality of service for different services on W-CDMA communication systems. However, perfect power control is very difficult to realize in fading environment. In this paper, the effect of step size of power control on the received power under shadowing and fading is simulated. The effect of power control on the capacity of W-CDMA communication system is analyzed and the numerical
results are given. The results are valuable for the design of W-CDMA communication systems.
