Abstract

The paper presents a power control compensation method in the forward channel for the higher system capacity of the future Multi-Service hierarchical CDMA system. This method is mainly based on the confidence level and the estimation theory. The estimation has two steps, the channel fading estimation and the Mobile Station (MS) traffic amount estimation. The simulating results prove that it is better than the traditional power control methods by the great reduction of outage probability about 15%.
