Abstract: A novel decisive algorithm based on signal-to-interference power ratio estimation has been proposed to control the power transmission of the mobiles in a code-division multiple-access mobile radio system under multipath environment. A simple second-order equation, together with three different sets of measurement and power-control periods, is first used to predict the power gains of the channels. Based on the predicted power gains, five decision rules have been proposed to determine the power-control commands for the mobiles. The novel algorithm with the best prediction method and decision rule has been observed to accomplish a lower outage probability when compared with the conventional power-control algorithm with optimum power-control threshold.
