摘要 构造了一个基于合作博奕的非对称纳什协商效能函数,并通过2个认知用户间协商子载波的使用,实现了基于感知贡献加权的比例公平性频谱分配的新算法。仿真结果表明提出的方案不仅实现了频谱资源的公平有效分配,而且有利于频谱感知的最大化。 In cooperative game asymmetric-Nash-bargain-solution-based utility function was proposed and the new spectrum allocation algorithm based on sensing contribution weighted proportional fairness through two cognitive radios bargaining was implemented. The simulation results show that the approach realizes not only efficient and fair allocation of the spectrum resource but also maximization of the spectrum sensing.
