摘要

To demodulate the received bursts correctly, the timing of reception of the bursts is predicted by a receive timing controller (29) which receives the frame timing control information from the frame timing function (14) and parameters of the satellite (4) from the hardware adaptation layer HAL (10). These parameters define the position of the satellite and of its beams and allow the timing of arrival of data bursts from the mobile access node to satellite access node to be predicted. An independent claim is also included for a wireless link signal comprising a data burst including in temporal sequence, a method of receiving signal over a wireless link.
