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