Hi, Mueller
Thanks for your rely!
Are there any good gnuradio QAM mod/demod examples (Do not use QAM
modules) to learn ?
Thanks！

Dear Eric,
the QAM Demod and Mod blocks are deprecated. Thus, please don't use
them! We can't help you if anything doesn't work, and they randomly
drop data.
I confused about the output data format of the QAM Demod module and
how to deal with them.
That output is just the bits contained in the QAM modulation.
I can't with a good conscience tell you what *not* to use without
telling you *what* to use. So:
go into your /usr[/local]/share/gnuradio/examples/digital/packet.
You'll find packet_loopback_hier. By default, it's configured to be a
QPSK, but you can change the Constellation object to your heart's
delight. Try with the default first! That's a 4-QAM right there ;)
Best regards,
Marcus

Hi， ALL
Are there any good examples or documents to teach me how to use the " QAM Demod
" module?
I confused about the output data format of the QAM Demod module and how to deal

And why QAM demod do not output a complex data?
I also found the description of the "QAM Demod" block is the same as "QAM Mod"
module.
Any documents tell us how the QAM demod works?
Thanks very much!
