摘　　要：无线资源管理对实现资源的有效利用起着至关重要的作用。针对变电站中无线网络资源分配问题,提出了基于非合作博弈的变电站无线网络资源的优化管理算法,解决了全双工系统的无线电资源分配问题。将下行链路与上行链路的联合速率最大化问题建模成为上下行链路信道之间的非合作博弈,提出了基于非合作博弈的迭代算法。该算法有效的实现最佳上行链路与下行链路的资源分配,直到达到纳什均衡。仿真结果表明,该算法实现了快速收敛,与同等资源分配方法相比,可以显著提高全双工的性能。Wireless resource management plays an important role in the effective utilization of resources.Aiming at the resource allocation problem of wireless network in substation,this paper proposes an optimization management algorithm of wireless network resources in substation based on the non-cooperative game,which solves the radio resource allocation problem of full duplex system.The problem of maximizing the joint sum rate of downlink and uplink is modeled as a non-cooperative game between uplink and downlink channels,and an iterative algorithm based on non-cooperative game is proposed.The algorithm can effectively achieve the optimal uplink and downlink resource allocation until the Nash equilibrium is achieved.According to analysis of simulation result,the algorithm achieves fast convergence and can significantly improve the performance of full duplex compared with the existing resource allocation method.
