Survey on cognitive anti‐jamming communications [PDF]
IET Communications, 2020 In this study, the authors review various jamming and anti‐jamming strategies in the context of cognitive radios (CRs). The study explores different jamming models and classifies them according to their functionality. Furthermore, a study of jamming detection techniques is provided to enable a CR to identify different jamming signals.

Researchment of Mainlobe Anti-jamming Algorithms
Journal of Physics: Conference Series, 2020 Abstract Main lobe interferences usually cause the distortion and peak offset of main lobe and the heighten of side lobe level in adaptive beamformers. The block matrix algorithm utilized the direction vector which was determined by both the antenna arrays and the direction of interference to eliminate the main lobe interference.
