Abstract
Modern wireless systems utilize non-orthogonal multiple access to increase their rate capacities; however, the efficiency of the individual utility defined in bits per Joule has yet to be considered. Multiple variations of non-orthogonal multiple access have the interference of the signal-to-interference-plus-noise ratio as a function of the received power from multiple other users due to code implementations that are non-orthogonal or non-ideal cancellation in successive-interference-cancellation methods. Game theoretic concepts are used to improve user bits-per-Joule performance. Previous solutions increment transmit power and are not based on closed form systematic methods. The mechanism design presented here led to a non-cooperative Nash equilibrium solution based on detrimental inter-user effects. The resulting algorithm not only converged but also yielded a Nash bargaining and Pereto optimal solution that Pareto dominated the non-cooperative solution sans mechanism. Operating power may decrease 20 dB–45 dB, while utility gains may increase between 28 dB–46 dB.
