Hi everyone,
I currently use GRC 3.7.9.1 and only its In-Tree-Modules.
PC: Lenovo Laptop W530
CPU: Intel i7-3610QM with 8GB RAM
OS: Ubuntu 16.04 64 bit
I tried to create some easy examples of different modems. My first goal is
to modulate ASCII- or WAV-files, add some noise, demodulate the data
Hi Chris,
I've been using GNURadio for sat comm like this for a while, as have
others. It's a great tool for the job! To be frank though, this is more
than a $500 hit job. Good luck in your search.

Hi Chad,
So, I've went ahead and built a refreshed uhd RPM for CentOS 7. I really
haven't had a chance to test it (and it's getting all kinds of late
around here), but if you'd like to try yourself:

I have a project that requires a gnu radio receiver that can receive,
demodulate, and decode BPSK and QPSK data coming from a satellite modem.
The modem also has FEC that will need to be handled.
I can provide remote access to our lab machine that has a USRP connected to
our modem for testing.

So is that what the time_est tag in corr_est_cc is for? The idea being
correlate against the preamble to generate an initial timing estimate for the
clock recovery to lock quickly?

For what it's worth, I have both working fine on a c7 box here, I did it
from source though, not through pybombs. I had to build a couple packages,
such as boost, but it definitely can be done, at least as of a few months
ago.

Both blocks are meant for continuous signal and will take a "while" to lock.
Usually for bursts, you have a sync seq
I want to use the polyphase clock sync block to match filter and clock sync on
a bursty signal. The pulse shape is basically square, but from our discussion
[1], providing RRC taps works pretty well. I have snippets (~20k samples) of
the signal from an energy detector, which contain the burst
So, I just tried building UHD through pybombs, which had its
strangenesses, but worked out.
Which also means that you should be able to install it from source
manually without pybombs. I'm currently doing a pybombs --prefix

Hi all,
I was taking a closer look into the CCSDS 27 blocks and noticed that the
polynomials may be wrong?
The viterbi.c code says NASA code which has the polynomials 0x6D and 0x4F.
However CCSDS is ordered 0x4F followed by 0x6D with an inversion on the
0x6D output. I see that the butterfly cells

No. It should be. In fact, I've built it once, but that was a while
back, but I don't remember UHD giving me much trouble.
I'll try again later today, please stand by.
Best regards,

All I really need in the short term is UHD on CentOS 7.
Is it the consensus of the group is that UHD/gnuradio is not
installable
on CentOS 7? I haven't seen any suggestions about the python-zmq
problem below.

Hi Marcus, The reason I went with sudo was because it was erroring out
if I didn't:
$ pip install -I --user pybombs
Collecting pybombs
Using cached PyBOMBS-2.2.0.tar.gz
Complete output from command python setup.py egg_info:
/usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown
Hi Jason,
the --user flag installs into a user directory suitable for the user
calling pip – by using sudo, that user is root; recommendation: remove
this install again, and then run the same command without sudo :)
Best regards,
Marcus

Alright, after some mucking about I may have made a bit more progress.
running: sudo pip install -I --user pybombs

Looks like its clashing with you first attempt. Maybe remove that first.
Also, if you do install with --user you need to add $HOME/.local/bin to
your PATH variable.

Python usually doesn't look for packages in /usr/local/
That can be changed, of course.
However, maybe you should consider installing pybombs somewhere else.
For example,
pip install --user pybombs
or
pip install --user PATH_TO_YOUR_PYBOMBS_CLONE_OR_TARBALL
should work nicely.

That was indeed my first issue. I don't know that I would blame pip for
