论文摘要
鉴于MMWave通信中视线的重要性，战略对手可能会通过阻碍接收者来损害传播，而接收器反过来又可以通过试图绕过这一障碍来做出反应。为了扩展这一点，我们从游戏理论的角度研究了一种这样的方案，考虑到移动MMWAVE接收器和对手在零和游戏中以战略性的互动，他们希望在其中最大化或最小化通信的光谱效率。为此，对手试图筛选接收器的视线作为障碍物，而接收器可以四处移动以避免堵塞。我们认为预设距离，玩家可用的选择是改变其角度坐标以相互走动。这是一个静态信息的静态游戏，为此，我们在数字上找到了混合策略中的NASH平衡，得出了一些有趣的结论，例如将其与发射器的光束成型模式相关联。
Given the importance of line-of-sight in mmWave communications, a strategic adversary can harm a transmission by obstructing the receiver, which in turn can react by trying to move around this hurdle. To expand on this point, we study one such scenario from the perspective of game theory, considering a mobile mmWave receiver and an adversary interacting strategically as players in a zero-sum game, where they want to maximize, or respectively minimize, the spectral efficiency of the communication. To do so, the adversary attempts at screening the receiver's line of sight as an obstacle, while the receiver can move around so as to avoid the blockage. We consider preset distances and the choices available to the players are to change their angular coordinates to go around each other. This is framed as a static game of complete information, for which we numerically find the Nash equilibrium in mixed strategies, drawing some interesting conclusions such as connecting it with the beamforming pattern of the transmitter.
