Abstract :
A new scheme to distributed share spectrum employing MIMO-OFDMA-based Cognitive Radio is proposed. First an asymmetric-Nash-bargain-solution-based utility function is developed. And a new spectrum sharing algorithm based on sensing contribution weighted proportional fairness is implemented through multi-user optimal matching and two users bargaining. The experimental results show that the approach not only realizes efficient and fair sharing of the spectrum resources but also maximizes the potential of the spectrum sensing.
