Research on spectrum sensing of Multiple UAVs Based on Group Cooperative

Given the problem that the detection performance of the current multi-UAV cooperative spectrum sensing algorithm is not so good, this paper comes up with a multi-UAV spectrum sensing algorithm based on group cooperation. Firstly, a multi-UAV cooperative sensing architecture model is constructed, and secondly, a cooperative spectrum sensing method based on the combination of feature extraction and clustering algorithm is proposed. Finally, the simulation results show that the method proposed in this paper outperforms the traditional method under the condition of low SNR. Better detection performance is the advantage of collaborative sensing algorithms, multi-UAV swarms communicate with each other to achieve collaboration, can accurately perform collaborative spectrum sensing tasks, and have broad application prospects.
