In this paper, in order to decrease the interference between secondary users and primary users, a power control model based on the cooperative game theory has been investigated in the cognitive radio network. According to Nash theorem, a new utility function based on a fairness function is designed, and a new distributed power control algorithm based on Nash Bargaining Solution (NBS) is also put forward...
A unified system model for multirate multiple-input multiple-output (MIMO) multicarrier code division multiple access (MC-CDMA) systems is proposed in this paper. Based on the proposed unified system model, a novel space-frequency minimum mean-squared error based successive interference cancellation receiver (SF-MMSE/SIC) is developed and analyzed. The signal processing of this new detector is jointly...
