An adaptive fixed-step power control algorithm based on link quality measure

A simple adaptive fixed-step power control algorithm for mobile cellular systems is proposed. While most of the power control algorithms are based on the received signal-to-interference ratio (SIR) to adjust the transmitter power, our algorithm can be based on any generic link quality measure. The bit error rate (BER) measure is such an example. Our algorithm does not require the knowledge of the exact relation between the link quality measure and the SIR. As long as the link quality measure changes monotonically with the SIR, our algorithm is proven to converge to a specified target region
