摘要
指出多小区无线数据系统中基于非合作博弈的功率控制算法的纳什均衡不是帕累托最优的。 提出一种新的适用于多小区无线数据网络的基于最佳等信干比的功率控制算法,使系统中每个小 区的终端都工作在最佳等信干比下。仿真结果表明,该算法明显提高了系统的性能,使系统终端具 有相对较高的效用和较低的发射功率,并使得无线网络资源的使用更加合理和公平。
Abstract
It’s indicated that the result of Nash equilibrium of noncooperative power control game in multicell wireless data networks can’t be Pareto optimality. A new power control algorithm based on best equal SIR is presented for multicell wireless data networks. Numerical results suggest that this algorithm can improve capability of the system, make terminals enjoy higher utility and lower transmit power, and the use of wireless resources become more rational and impartial.
