Abstract
Transmitter power control has been shown to be an efficient and effective means for supporting variable-service users in wireless networks. In this presentation, an estimator-based controller is proposed for distributed uplink power control. The controller is optimal with respect to minimizing a cost function consisting of a user's signal-to-interference ratio (SIR) error and the network interference, in a decentralized manner. Assuming sufficiently good estimates, the controller has the potential of providing convergence in a few iterations. The main feature of the proposed controller is that it saves the user transmit power while achieving a satisfactory SIR value. Furthermore, 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.
