Hi!, I want receive dvb-s2 acm through usrp. Is it possible? Only I found to transmition... thanks!

drmpeg commented 6 years ago

It's is not possible today. It's very difficult to have an LDPC decoder that works fast enough in software.

How about Cuda or other hardware acceleration?

drmpeg commented 5 years ago

I've made some progress. You can find some receiver blocks here.

The LDPC decoder relies on processing multiple frames in parallel, so it's not useful for VCM/ACM.

Guess i have to go back to school i thought whole point of hardware acceleration via GPU was parallel processing heh. anywhoms Thank you for your work Gonna check out that and see what's up tomorrow decided today is beer day

This can be closed since both LeanDVB and Markro92's GUI version can both demod in real time, for good SNR and with decent hardware. Edit: not possible for acm.
