Hello,everyone !
This is my frist time to this forum .I am a student live in xinjiang province China .
My english is bad ,please don't ridrcule me Sad
I am very interesting in satellite communicating, and this is my professional too. For these day ,I am stduying the Turbo Prouct Code, I have known the Comtech EFdata company's Turbo Prouct Code structure .Include the 1/2 3/4 7/8 0.95 TPC , It's Sync frame is 20768 2964 16320 4032 Bit.
Recently, I meet a strange signal , It's modulate type is QPSK, Sync frame=32200Bit,  Sync mark block=24Bit, I guess it's a unknown Turbo Prouct Code, Can you tell me what it is ? and what modem modulated it?
Last, if you can tell me the other major satellite modem's TPC structure (include the LDPC),, I would be very thankful!
