| 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。

| Abstract: | 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. |
