Hello together,
i've just started to play with GNU Radio and i use a DVB-T USB Stick
(Tuner R820T) as Source. I've already built a FM receiver and now i want
to listen to DAB. My signal processing skills are on a rookie-level. So,
my question is, is it possible to create a DAB receiver with
the standard blocks in GRC (gnuradio 3.7)? Would it be possible to use
the OFDM receiver? I found this website
The OFDM receiver is geared towards packetized data. It might work, but
you'd need:
- A synchronization algorithm
- A better equalizer
- A definition for the packet format.
I would consider these things above rookie-level, but that's not to
discourage you from trying :)
Also, there are many projects out there for digital radio. There's
gr-drm (not sure if it includes a full rx, though) and I thought there's
a GNU Radio DAB rx out there (ask the Googles).
And DVB-T is not *that* different, and we have GNU Radio codes for that,
too.

for a complete DAB Receiver, but it needs the gnuradio-core, which only
exists in older gnuradio versions.
Transitioning to the new version should be simple if you're just using
stock blocks. There's a wiki page on the transition which will help you
porting.
Cheers,
