Application of the generalized predictive control method in closed-loop power control of CDMA cellular communication systems

In this paper we investigate adaptive closed-loop power control algorithms based on the Generalized Predictive Control (GPC) method that are able to alleviate the effect of the loop delay inherent in the closed-loop power control of DS-CDMA systems, even if the loop delay is unknown. The numerical results indicate that the GPCbased algorithms can significantly improve the radio network capacity without any increase in power control signaling, even with unknown loop delay.
