[Discuss-gnuradio] DRM receive

[Jiri Pittner]

Hi,

did somebody try to use gnuradio for receiving DRM (Digital Radio Mondiale)?
It seems to me that neither M-QAM demodulation nor the apropriate audio codec
is presently implemented in gnuradio, however, the DRM program "dream" has
an option --fileio, which should be able to replace the sound card as the source
of the IF samples. So I think until everything is available in gnuradio, 
it should be possible to do the RF processing with gnuradio (using basic-rx 
and some preamplifier) and feed the frequency-translated data to dream, which 
would do the rest.
Does anybody know the format of the data which dream --fileio expects?
Did somebody try this approach before, with/without success?

Best regards,

Jiri
