Timing synchronization with a modified DVB-S2X waveform for a beam hopping satellite
Abstract:
A system and method for timing synchronization with a modified DVB-S2X waveform for a forward beam hopping satellite is described. The method includes: transmitting a channel including a plurality of beams per a Beam Hopping Time Plan (BHTP), wherein each beam includes a discontinuous signal including a superframe including timing markers and a Beam Hopping Forward Synchronization Pattern (BHFSP); receiving a synchronization information, without a loopback beam, for one of the plurality of beams; determining an adjustment period and an adjusted symbol rate for generation of terrestrial switching instants, based on the synchronization information, for a transmission of the plurality of beams such that at least a portion of a respective BHFSP of one of the beams aligns with one of satellite switching instants; and adjusting a timing and symbol rate of the transmission according to the adjustment period and the adjusted symbol rate, respectively.
