| 摘 要： | 从认知无线电技术特性出发，在干扰温度门限的限制条件下，提出了基于新的代价函数功率控制博弈论算法，以有效地提高认知用户的信干噪比。根据信道状况、吞吐量最大化和功率限制的需求，将功率控制问题转化为一个干扰受限的多约束非线性规划问题。结合博弈论和最优化理论，证明了其纳什均衡的存在性和唯一性，给出了该模型的分布式求解算法。仿真实验表明，该算法可以有效提高认知用户的QoS和系统性能，充分利用无线资源。

| Abstract: | A novel non-cooperative power control algorithm based on new pricing function and the characteristics of cognitive radio technology was proposed with the interference temperature constrain,in order to improve signal to interference plus noise ratio of CR.The problem of power control was changed into the problem of multi-restraints non-linear optimization with interference limits based on channel conditions,maximal network and power limits.The existence and unique of nash equilibrium(NE)in utility function by the principle of game theory and optimization were proved and a distributed algorithm for this game was proposed.Simulation results show that the proposed algorithm can improve users QoS(quality of serves),system performance effectively and improve radio resource efficiency. |
