This research aims to develop a robust beamforming strategy to enhance uplink communications for LEO satellites facing co-channel interference.
Developed a database-aided adaptive beamforming framework with three main stages: local spatial refinement, truncated adaptive amplitude estimation, and INCM reconstruction.
Implemented a constrained Capon search to localize interferers while safeguarding the desired signal.
Conducted simulations to compare performance against existing methods under different interference conditions.
Achieved near-optimal signal-to-interference-plus-noise ratio (SINR) with significantly improved spatial statistics estimation.
Showed consistent performance gains over DL-MVDR, ESB, and IAA methods under varying signal-to-noise ratios (SNR) and interference-to-noise ratios (INR).
Demonstrated strong robustness and practical applicability of the proposed approach in real-world settings.
