Abstract:

Since the hybrid beamforming HBF can approach the performance of fully digital beamforming FDBF with much lower hardware complexity we investigate the HBF design for beam hopping BH low earth orbit LEO satellite communications SatComs Aiming at maximizing the sum rate of totally illuminated beam positions during the whole BH period we consider joint beamforming and illumination pattern BIP design subject to the HBF constraints and sum rate requirements To address the nonconvexity of the HBF constraints we temporarily replace the HBF constraints with the FDBF constraints Then a joint FDBF and illumination pattern design scheme is proposed using random search and fractional programming FP methods Based on the designed illumination patterns we optimize the digital beamformers with the constrained analog beamformers by utilizing the FP methods where a sum rate maximization HBF scheme is proposed Simulation results show that the proposed schemes can achieve satisfactory sum rate performance for BH LEO SatComs
