| 摘 要： | 针对认知无线电中博弈功率控制算法的特点,对代价函数进行改进,提出了一种基于信干比的非线性代价函数博弈功率控制算法(NPGP-NL),证明了NPGP-NL算法纳什均衡的存在性和唯一性,并用Matlab软件对NPGP-NL算法做了仿真,结果表明:NPGP-NL算法使认知用户的发射功率降低,效用提高,且在一定程度上兼顾了系统的公平性。 |

| Abstract: | Considering the characteristic of game power control algorithm in cognitive radio,the pricing function is improved and power control game via nonlinear pricing function based on signal-to-interference ratio(NPGP-NL)is proposed,then the existence and uniqueness of the nashequilibrium are proved.Meanwhile,NPGP-NL is simulated via Matlab,and the simulation results show that NPGP-NL not only reduces emission power of cognitive user and improves the utility,but also takes into account the system fairness to some... |
