Abstract

Recently, passivity-based techniques to control the transmit power of mobile nodes have been proposed to ensure the input-output stability of cellular CDMA networks. An inherent assumption in these solutions is that the transmit power synthesized by the controller of choice does not exceed an upper bound pmax, which has not been characterized. In practice, an upper bound pmax is invariably imposed on the instantaneous transmit power of the mobile user and may lead to windup in the cellular network. We propose an antiwindup mechanism.
