Re: [Discuss-gnuradio] DRM receiver

Hi Havard,

for transmission, gr-drm might be the way to go[1]. But since you asked
for reception: I wouldn't know of integration of dream into GNU Radio so
far. However, if I'm not mistaken, dream can use both a sound card for
IF input as well as for baseband IQ input -- and with a sufficient
amount of ALSA magic, you might build a GNU Radio -> Audio Sink ->ALSA
pipe -> Dream thing. Note that I think this should be possible, but
never had the nerve to configure ALSA correctly.
The other option would be using the file source, to read a wav file
which would effectively be FIFO to which GNU Radio writes. I'm not too
confident this will work out of the box, because WAV files have a
footer, and that will be problematic for streaming, but if Dream is
built with libsndfile, I guess you'll be able to just use raw GNU Radio
file sink data, and specify that the data is stereo float32 raw PCM
without a header. Not having used Dream myself, I don't know whether
that's the optimal solution, or viable at all without modifications to
Dream.

Best regards,
Marcus
