Channel estimation for Digital Video Broadcasting via Satellite (DVB-S2)

摘要

To allocate a VSAT to a MODCOD in a DVB-S2 ACM system, the HUB periodically transmits pilot frames of alternating MODCODs, which is identified by the VSAT. An FPGA at a VSAT site maintains telemetry of good and bad frames. A processor polls this telemetry to determine the optimal MODCOD to be allocated to the VSAT.
