Energy-Efficient Power Control and Receiver Design in Relay-Assisted DS/CDMA Wireless Networks via Game Theory

Non-cooperative power control strategies for the uplink of relay-assisted DS/CDMA wireless networks are considered in this paper using game-theoretic tools. Assuming that each user is interested in maximizing his own energy efficiency, measured in bit/Joule and denoting the number of error-free delivered bits for each energy-unit used for transmission, several non-cooperative games are proposed and analyzed. Simulation results confirm the theoretical findings and show that the use of advanced data detection strategies has a huge and benefic impact on the energy efficiency of relay-assisted wireless networks.
