一局

There is mutual contradiction between direction estimation of user's signal and power allocation among all users in the beamforming algorithm. A twice game beamforming algorithm based on game theory is proposed to deal with it. Beamforming game algorithm mathematics model is constructed. During the first game, direction of signal and power allocation are mapped the game theory as "player", which are modeled as the problem of maximin function and obtain direction estimation first. Then during the second game, power allocations of different users are described as a multi-user game. Power updated algorithm is designed. The existence and uniqueness of the Nash equilibrium in the twice game beamforming algorithm based on game theory are proved by mathematics derivation.

摘要针对波束成形算法中，用户的信号方向估计值和用户之间的功率分配存在着相互矛盾，本文提出了一种基于博弈论的二次博弈波束成形算法，构建了波束成形博弈算法数学模型，首先在第一次博弈的时候，将波束成形算法中的信号方向和功率分配映射为博弈论数学模型中的"局中人"，将其建模为函数的极大极小值求解问题，先求解出信号方向；然后在第二次博弈的时候，将不同用户的功率分配过程描述为一个多用户的博弈过程，设计了功率分配更新算法，通过数学推导论证了纳什平衡点的存在性和唯一性。

O'Rourke's words had "the average life-span of a trout-stream mayfly hatch". His election-winning alliance in 1997, principle laid aside, was with the founder of the KCIA.

O'Rourke的话说，"其平均寿命就像鳟鱼溪里一只蜉蝣的孵化时间"。1997年他的选举获胜的联盟竟然还包括韩国中情局的创立者，毫无与原则性可言。

Based on the Green function technique,the authors have analyzed the effect of the decoupling approximation on treating the interelectronic correlations and then calculated the local moment,hybridization matrix element,and ground state energy of the one dimensional,symmetric,periodic Anderson model.

基于Green函数技术，作者首先分析了切断近似对处理一维对称周期Anderson模型中电子间关联的影响，然后计算了该模型的局域磁矩、杂化能量元和基态能量。

Adopting the conformal mapping or rotation axis etc complex methods which areoften used to treat with the hole or cavity problem,a two-dimensional cavity ofeither simply or multiply connected region is projected into the interior of acircle or an annulus.As well as the global coordinate system is turned into thelocal coordinate system.
