摘要: 为解决无人机集群网络在复杂通信环境中对抗智能性干扰能力较弱的问题,基于智能决策理论,提出一种多域联合的认知抗干扰算法。该算法在优势演员-评论家算法的基础上,将无人机视作智能体,并由感知到的环境频谱状态决策出干扰信道。基于Stackelberg博弈理论,利用功率域压制中度干扰等级的信道干扰信号,减少切换信道的时间开销。通过引入簇头协助的方法,解决由于单个智能体局部频谱感知能力较弱而导致信道决策成功率较低的问题。仿真结果表明,相比QL-AJ算法与AC-AJ算法,该算法能够给出簇内最佳节点个数,提高接收信号信干噪比,且网络整体抗干扰性能较好。

Abstract: To solve the problem of weak ability of Unmanned Aerial Vehicle(UAV) cluster network to resist intelligent interference in complex communication environment,this paper proposes a multiple domain cognitive anti-jamming algorithm based on the intelligent decision-making theory.Based on the dominant actor-critic algorithm,the algorithm regards UAV as an agent and the jamming channel is determined by the perceived environmental spectrum state.Based on the Stackelberg game theory,the interference signals of the middle-level interference channels are suppressed from the power domain to reduce the time cost of channel switching.Cluster head assistance is introduced to solve the problem of low success rate of channel decision-making due to weak local spectrum sensing ability of a single agent.Simulation results show that compared with the QL-AJ algorithm and AC-AJ algorithm,the proposed algorithm can give the optimal number of nodes in the cluster,improves the Signal to Interference-plus Noise Ratio(SINR) of the received signals,and provides better overall anti-jamming performance for networks.
