Newton Iteration Acceleration of the Nash Game Algorithm for Power Control in 3G Wireless CDMA Networks

In wireless communication systems, each user's signal contributes to the interference seen by the other users. Given limited available battery power, this creates a need for effective and efficient power control strategies. These strategies may be designed to achieve Quality of Service (QoS) or system capacity objectives, or both. The authors show how the power control problem is naturally suited to formulation as a non-cooperative game in which users choose to trade o between Signal-to-Interference Ratio (SIR) error and power usage.
