Aldajani, M.A. and Sayed, A.H. (2003) Adaptive predictive power control for the uplink channel in DS-CDMA cellular systems. Vehicular Technology, IEEE Transactions on, 52.
In this paper, we analyze the conventional closed-loop power-control system. We explain that the system behaves essentially as a companded delta modulator and then derive an expression for the power-control error in terms of the channel fading, which suggests methods for reducing the error variance. This is achieved by using a prediction technique for estimating the channel-power fading profile. The prediction module is combined with several proposed schemes for closed-loop power control. The resulting architectures are shown to result in improved performance in simulations.
