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
