Abstmef-Most distributed power control algorithms have been proposed assuming constant interference and constant path gain. These considerations may result in lower performance gains in fast time-varying channel conditions. The two algorithms presented herein address this problem efficiently and the first is also a generalization of other previously studied distributed power control algorithms.

In this contribution game theory concepts are applied to the decentralized power control problem in a WCDMA wireless data system. We propose a new distributed power control algorithm which is derived from the formulation of the power control problem as a static multi-stage nonzero-sum noncooperative game. It performs the choice of a suitable operation point, improving the overall system performance in an energy efficient manner. * V. A. de Sousa Junior and R. A. de O.
