In this paper, the authors propose a non-cooperative joint modulation, rate, and power control game-theoretic approach for the uplink of a single cell CDMA system. A generalized approach towards adaptive modulation is introduced, by fitting different efficiency functions of several modulations by means of the Gompertz sigmoid functions. The existence of Nash equilibrium as well as the best response strategies for their game is then derived. An iterative algorithm to select the best power and rate values for the desired modulation is presented, reaching the equilibrium in a distributed manner.
