摘　　要：针对认知无线电系统中功率控制的问题,根据David Goodman的非合作博弈思想,设计了一个基于干扰温度的代价函数,并对效用函数中的有效函数作了改进,在此基础上提出一种基于干扰温度的功率控制博弈算法。在仿真分析中同几种常用的功率控制博弈模型作了对比,结果表明该算法能有效提高认知用户的帕累托效应,提高用户的吞吐量,保障认知用户和主用户的QoS需求,使网络资源得到平等共享。Aiming at the power control in cognitive radio, according to the non-cooperative power control game which was created by David Goodman, a power control game algorithm based on interference temperature was discussed. The efficiency function was improved. We also designed a new pricing function with interference temperature. Compared with other power control game models simulation shows that the NPG-ITLP algorithm improves the Parteo efficiency, and enhances the system throughput, guarantees the QoS （ quality of service） of the secondary users and primary users. It also realizes resource allocation equality in cognitive radio network.
