Predictive Closed-Loop Power Control for CDMA Systems in Time-Varying Fading Channels  

Choe, Sang-Ho (School of Information, Communication & Electronics Engineering, The Catholic University of Korea)
Abstract
In this paper, we present a novel predictive CDMA closed-loop power control (CLPC) method with a multi-step least squares (LS) linear predictor for time-varying fading channels. The proposed method effectively compensates multiple power control group delays and provides significant performance gains over nonpredictive CLPCs as well as conventional predictive CLPCs with one-step linear predictor.
