Hi all,
Sorry to introduce so late, but I want to share my GSoC 2014 proposal
about improving PyBOMBS. It is available on Github [1], and I mentioned
the link in Google Melange. I was busy with several urgent tasks and
risks missing the GSoC. Hope now is still in time.
I would like to thank for t

Hi all,
Recently I have upgraded my gnuradio build to v3.5.3 on several
computers, and I find that on two machines with Ubuntu 11.10, make test
will fail the test qa_constellation_receiver while on the other two with
Fedora 16 all tests are passed.
To investigate the problem, I add one line in th

Hi folks,
I think the calculation of symbol rate on line 73 of
gr-digital/examples/narrowband/digital_bert_rx.py contains a bug. Here
is the line:
self._symbol_rate = self._bitrate * self._demod.bits_per_symbol()
It should be / rather than *, right?

Hi all,
I meet a strange behavior when building gnuradio (v3.5.3.X) on my
desktop with Fedora 16 these two days.
When I build in the directory build/:
rm -rf *
gr-cmake # my script which call cmake with some options enabled
make -j 8 && make test
The test 'qa_pmt' always fail. When run
./
Hi list,
I am experimenting with narrowband benchmark_tx/rx in real indoor air
interface. The software is GNU Radio 3.5.3.2 and the hardware available
is USRP with RFX2400 daughter boards.
When I use gmsk modulation to transmit and receive, the performance is
quite good - very few packets are los

Hi list,
I build a flow graph with both transmitter and receiver, and the forward
path works fine. Then I want to let receiver block to feedback some data
to the transmitter block, and I learn that GNU Radio does not allow the
flow graph has loops. Now I'm trying to walkaround the limitation by
us
Sorry I forgot to CC my last email to the list. Below is Josh's reply
with my walkaround (quoted).
