Abstract

The energy efficiency (EE) maximization on the uplink of multicarrier code division multiple access (MC-CDMA) cooperative wireless networks is a NP-hard optimization problem of great interest for future networks systems. This paper presents two different noncoalitional game theoretic approaches to solve in a distributed fashion the EE maximization problem that arises in MC-CDMA wireless cooperative networks considering receiver multiuser filter design. A study over the quasi-concavity of the utility function is presented while numerical results and a complexity analysis are offered to corroborate the mathematical model and observe the tradeoff between EE, spectral efficiency, and average transmission power.
