摘要

Transmitter power control has been shown to be an efficient and effective means for supporting variable-service users in wireless networks. In this paper, an estimator-based algorithm is presented for distributed uplink power control. The controller is optimal with respect to the minimization of a cost function consisting of a user's signal-to-interference ratio (SIR) error and the network interference. Assuming sufficiently good estimates, the power control algorithm has the potential of achieving convergence in a few iterations. The issue of joint minimization of network interference and a user's SIR error is addressed in a distributed manner so as to obtain a desired tradeoff.
