| 摘 要： | 简要介绍了博弈论的基本原理和非合作博弈功率控制模型,为了改进非合作博弈中终端的不公平性,将合作博弈引入到功率控制中来,使得系统中所有终端都工作在最佳的等信干比下,并推导出一个分布式基于合作博弈的功率控制算法.仿真表明,该算法明显提高了系统的性能,系统中终端具有相对较高的效用和较低的发射功率,还使得无线网络资源的使用更加合理和公平,同时算法拥有较好的收敛性.

| Abstract: | The basic principle of game theory and the model of non-cooperative power control game(NPG) presented for wireless data network are introduced.In order to ameliorate unfairness between terminals in system,the idea of cooperative game is introduced to this model;a new distributed algorithm based on cooperative game(CPG) is presented.Numerical results suggest this algorithm can improve the capability of the system;terminals have higher utility and lower transmit power relatively,make terminals use the wireles... |
