To optimize beamforming techniques for low Earth orbit satellite communications amidst inter-beam interference.
Introduced spacetime zero-forcing (ST-ZF) and space-time signal-to-leakage-plus-noise ratio (ST-SLNR) techniques.
Analyzed performance in partially connected interference channels and general interference networks.
Compared results with conventional methods like maximum ratio transmission.
ST-ZF achieved a 3dB SNR gain over conventional methods.
ST-SLNR significantly enhanced sum spectral efficiency compared to traditional interference management approaches.
Proposed techniques effectively improve interference mitigation for LEO satellite communications.
