An Adaptive Beamforming Anti-Interference System Based on Software-Defined Radio

This paper proposes an adaptive beamforming anti-jamming communication system, in which baseband signal processing is implemented on a software-defined radio (SDR). This approach offers programmable and flexible configuration features compared to traditional RF front-ends. By deploying adaptive filtering algorithms on the SDR platform, the system can adaptively weight and sum the signals from various channels, directing the beam towards the target signal with an unknown location. Ultimately, this achieves spatial filtering, enhancing the signal in the direction of the target while effectively isolating the interference signals.
