摘　　要：针对开放性频谱共享模型,提出了一种基于非合作博弈的自适应功率控制算法.该算法分为外部更新和内部更新,在外部更新时,用户进行周期性信息交互;在内部更新时,用户自适应控制功率.仿真结果表明,该算法与传统的分布式算法相比减少了信息交互量,并且能得到近似最优解.Based on hierarchy noncooperative game theory in open sharing model,a distributed algorithm used for adaptive power control is proposed. The algorithm is composed of outer updating and inner updating,in which each user can implement periodic information interaction and adjust its transmitted power adaptively. Through Simulation verifies that the information interaction can be decreased with the proposed when distributed updating,the near-optimal solution is obtained at the same time.
