This paper proposes a novel adaptive beam control mechanism for enhancing the performance of free-space optical (FSO)-based non-terrestrial networks (NTN), focusing on vertical satellite-HAP-UAV communication links. The system dynamically adjusts beam divergence and transmission rates based on channel state information (CSI) to address challenges such as atmospheric turbulence, beam misalignment, and cloud attenuation. Numerical results validate the effectiveness of the proposed approach in improving transmission rate and coverage. The findings highlight the potential of adaptive beam control in achieving high data rates and robust connectivity, aligning with the stringent requirements of future 6G communication networks.

摘要

This paper proposes a novel adaptive beam control mechanism for enhancing the performance of free-space optical (FSO)-based non-terrestrial networks (NTN), focusing on vertical satellite-HAP-UAV communication links. The system dynamically adjusts beam divergence and transmission rates based on channel state information (CSI) to address challenges such as atmospheric turbulence, beam misalignment, and cloud attenuation. Numerical results validate the effectiveness of the proposed approach in improving transmission rate and coverage. The findings highlight the potential of adaptive beam control in achieving high data rates and robust connectivity, aligning with the stringent requirements of future 6G communication networks.
