Research on Anti-jamming Algorithm of Multi-antenna System Based on Artificial Intelligence Technology

In order to solve the system interference problem caused by beamforming technology of multi-antenna system, an anti-jamming solution based on artificial intelligence technology is proposed, and a multi antenna anti-jamming model based on artificial intelligence algorithm is constructed. PSO algorithm is adopted to train and verify the rationality, convergence ability and performance of the model. Finally, the antenna array will form a great gain in the desired direction to improve the desired signal, while it will form a zero notch at the interference direction for interference suppression. It effectively improves the SINR (signal to interference ratio) of the receiver, and then improves the system performance and increase the system capacity.
