摘　　要：认知无线电技术通过提高频谱的复用潜力,解决了当前频谱资源紧缺问题.本文研究了在认知无线网络环境中,次用户帮助主用户转发数据的协作场景,提出了基于放大转发的协作功率及频谱资源分配最优化策略.仿真结果表明,论文提出的方案能够提高次用户的传输机会,并且可以降低主用户的中断概率.Order to alleviate the current shortage of spectrum resources,cognitive radio technology is proposed.A cooperative model in which primary and secondary user coexist,and the secondary user helps primary user forwards the data was studied in this paper and then it is described as a Stackelberg game.A cooperative power and spectrum allocation algorithm is investigated based on the game.Simulation results show that the proposed scheme can improve the transmission opportunities of secondary user,and can reduce the outage probability of the primary user.
