MANAGING DOPPLER AND FRAMING IMPACTS IN NETWORKS

摘要

A method (400) includes receiving a current velocity (340) and a current position (342) of a mobile node (120) relative to a fixed node (110), and identifying a receive time slot for the fixed node to receive a transmission of a data packet (10) from the mobile node and determining a propagation delay for the data packet based on the current position of the mobile node. The method includes determining a transmission time (350) based on the receive time slot and the propagation delay and determining a Doppler shift based on the current velocity of the mobile node. The method includes determining a transmission frequency (352) based on the Doppler shift and a clock rate correction (354). The method also includes transmitting the data packet to the fixed node at the determined transmission time using the determined transmission frequency compensated by the determined clock rate correction.
