摘　　要：为了提高频谱共享的有效性和公平性,提出了一个基于合作博弈的认知网络频谱共享模型和接入控制策略。博弈规则为在满足各用户最小收益的前提下,认知用户进行相互合作,并最大化总体收益;接入控制策略以满足服务质量需求为约束条件,并引入惩罚函数,迫使认知用户按照其实际需求竞争频谱资源。仿真结果表明:提出的合作博弈模型和接入策略提高了认知用户的总体收益和公平性,改善了系统中认知用户的满意度。In order to improve the efficiency and fairness of spectrum sharing, a spectrum sharing model based on cooperative game and an access control policy are proposed. Cognitive users cooperam with each other to maximize overall benefits on the premise of meeting users＇ minimum income. The access control policy takes the satisfaction of service quality requiremems as the constraint condition. A penalty function is introduced to fome the secondary users to compete spectrum according to their actual requirements. The simulation results show that the cooperative game model and the access policy pmpesed in this paper enhance the overall benefits and fairness of cognitive users and improve the cognitive users＇ satisfaction in the system.
