A novel closed-loop power control algorithm based on predictor

Power control is one key technology of 3G beyond and 4G mobile communication systems. In this paper, a novel closed-loop distributed power control algorithm based on predictor has been proposed. This algorithm can trace the variation of the radio environment changes and reduces the power control error caused by the time variation of the radio channels. Simulation results show that the convergence speed of this method is fast. This algorithm can be used to design and optimize the system parameters. So this method possesses a good perspective.
