Some Questions about leansdr in processing IQ file about leansdr HOT 8 OPEN

The spectrum is inverted in your IQ file. leandvb does not support that yet in DVB-S2 mode.

As a workaround you can flip the sign on each Q sample or swap each I/Q pair. Then leandvb should produce a 704x576 MPEG2 TS.

Thanks a lot. After I modify the IQ file, it works well.

@wufeissdfz Can you reupload your iq file? I can't download it by your link :( I wanna work with leansdr, but I haven't got any raw iq with DVB-S2.

@pabr I would be grateful if you would share this or a similar IQ file.

@klimentyev You can generate DVB-S2 IQ streams with tools that ship with leandvb, see:

However this will not simulate the specific issue that was present in the IQ file of @wufeissdfz, i.e. spectrum inversion.

Sorry for my reply late, I can generate DVB-S2 sample, what about the parameters of DVB-S2 IQ file.

@wufeissdfz Thx, but I wanna process the real signal for check my information data parser.
