A distributed non cooperative power control game with pricing (NPGP) for multiple-input multiple-output (MIMO) multi-carrier direct sequence code division multiple access (MC -DS/ CDMA) system for different modulation is considered in this work. The utility functions for assaying the performance of MIMO MC-DS /CDMA for spectral efficient communication of the system carrying wireless data are envisaged. The spectral efficiency and power efficiency are referred as utility which divulges the level of satisfaction a user may get. According to the utility functions, two NPGPpsilas are propounded, which determines the existence and individuality of the Nash equilibria. A novel power control algorithm that delves the performance of the anticipated power control games to achieve the Nash equilibria is presented in this paper. The simulated results elucidate that a significant amelioration in terms of utilities specifically spectral efficiency for all users can be achieved using this approach. Also the propounded scheme exhibits better performance in the MIMO MC-DS /CDMA in terms of spectral efficiency as compared to the traditional system.
