      Enhanced Publication
    • 基于天基物联网多普勒频率偏移预补偿的新型频率保护间隔调整方法
    • “In the field of space-based Internet of Things, a scheme based on Doppler frequency offset pre-compensation has been proposed to enhance spectrum utilization efficiency. This method can expand user access volume by 90-400 times and increase user access by an additional 45% or more, laying a foundation for the construction of space-based IoT system.”
