Abstract

A simple decentralized power control algorithm for communication systems with mobile users and unknown nonlinear and time-varying link gains is proposed and studied. We prove that the proposed algorithm is exponentially converging. Furthermore, we show that the algorithm significantly outperforms the well-known Foschini and Miljanic algorithm in the case of quickly moving mobile users.
