Abstract

We consider the problem of synthesizing decentralized transmit power control for finite-gain stable cellular code division multiple access (CDMA) networks subject to saturation constraints on the mobile transmit powers. We show that the passivity theorem and an extension of the Zames-Falb multipliers can be used to synthesize the required distributed decentralized nonlinear dynamic controllers, to be implemented at the base station and at the mobile users, including a multi-input-multi-output (MIMO) anti-windup controller that can be implemented on the mobile hand-sets.
