Distributed rate and power control for CDMA uplink

We consider a distributed CDMA system in which mobiles are able to control their transmission rate and power based on their radio conditions. Each mobile is assumed to be myopic, that is, its solitary goal is to maximize the payoff, which is the difference between the effective throughput and the price that the system charges for the received power on behalf of the mobile. We prove that the distributed system converges to a Nash equilibrium such that users near the base station transmit in the full rate while farther users transmit at the full power. Our simulation results present a numerical view of this distributed scheme.
