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. Aiming at the open spectrum sharing model, an adaptive power control algorithm based on non-cooperative game is proposed, which is divided into external update and internal update. During external update, users exchange periodic information. During internal update, Adaptive control of power.The simulation results show that the proposed algorithm can reduce the amount of information exchange compared with the traditional distributed algorithm and obtain the approximate optimal solution.
