Green power control and receiver design in relay-assisted interference channel wireless networks: a game-theoretic approach

Green resource allocation for relay-assisted DS/CDMA interference channels is considered in this paper. A non-cooperative game-theoretic approach is taken, according to which each user is selfishly 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 theoretically analyzed, and simulation results are provided to confirm the theoretical findings and show that the use of advanced data detection strategies can bring huge performance gains to the energy efficiency of relay-assisted interference channels.
