Distributed Power Balancing with Linear Prediction and Adaptive On-Off Strategies for CDMA Cellular Mobile Systems

Several distributed balance (DB) power control algorithms that can achieve SIRbalance have already been proposed for cellular mobile systems [1–3].In the present paper, two simple strategies, namely linear prediction andadaptive on-off strategies, are further applied to forward link distributedbalance (DB) power control in DS/CDMA cellular mobile systems. The linearprediction is used to track the variance of the short-term fading andcompensate it in advance, and the adaptive on-off strategy is applied to solvethe problem that the received SIR of all the communication links less than theminimum required SIR. Simulation results indicate that DB power control withthese two strategies can achieve much better performance than the original DBpower control.
