Abstract

In this paper, a novel algorithms based on neural-networks for the power control in the code-division-multiple-access cellular mobile systems is proposed, which is modified from the steepest gradient decent method. This scheme aims to predict signal-to-interference ratio affected by the channel variation at the receiver and issue appropriate control signal to the transmitter. The outage probability is used as the performance measure. Finally, simulation results show that the proposed method has an excellent prediction property
