You might consider a polyphase channelizer to pick specific OFDM carriers
out of the aggregate signal. They are very efficient in terms of CPU usage,
and so can even work at reasonably high input sample rates on decent CPUs
(with moderate GHz speed & number of cores). - MLD

Related to this general topic -- GR on ARM64:
The MacPorts maintainers of GR are soon going to update the main "gnuradio"
port ... we're proposing to the current 3.10 release. It is a pain to
maintain more than 1 related port, and we were waiting for many GR OOT
modules to be updated before we
Hi Mehmet - As nobody else has responded in any capacity, let me do so from
an Ettus Support perspective.
The reason your query isn't being answered is that it is highly technical,
with lots of details, and a very specific use-case that would require
someone many hours of work to process.

Hi Fred - In the top-level BUILD directory there will be a file
"CMakeCache.txt" where you can track down the exact variable names you need
to use for including the GR CMake variables. I think these are consistent
between different GR versions, but I really don't recall any longer & I'm
not
FYI for macOS users using MacPorts: I updated the "uhd-devel" port to the
current 4.0.0.0 release commit (20200913-90ce6062); the "uhd" port is still
at 3.15.0.0. Both ports should work with the "gnuradio" port for GNU Radio
3.8.2.0, and should install and execute under macOS 10.11 through
rc1, though I
don't know if this will even build.
I value any feedback on macOS building and/or use of UHD and GR (and Volk,
but that's pretty separate by now); MacPorts or some other install means;
any macOS version: 10.4-5 PPC 32/64, 10.4-16 Intel 32/64; even 10.16 ARM64

Hi Ivan - I'm assuming you mean configure and control a USRP's GPIO via UHD
in GNU Radio?
In theory this should be possible, at least in C++ and of course it
requires that the specific USRP have GPIO ...
I'm not sure if there's a Python GPIO API as of UHD 3.15, but if there is
then that method

The issue is how CMake decides to order "include_directories". There are
(if I recall correctly) 4 primary sources of these via properties: for the
directory, for individual sources, for to-be-built targets, and for linkage
targets. The ordering of these is critical, since our goal is to list
ding from the git source results in the same failure.

Hi Leo - What version of GR are you trying to use? This OOT requires GR37 to
build. Also, if you do ‘make VERBOSE=ON’ you’ll see the actual link command
which should be informative about the libraries being linked against. - MLD

it to install all of the IIO stuff? "port search iio" should come back with:

Hi Dylan - If you have access to a GR OOT module (e.g., "gr-example"), then you
can try to build it directly on your host computer ... as it sounds like you're
trying to do ... but without much success as it sounds like accessing GR
libraries for linking isn't working well.
Which version of GR
You're welcome, Chris. Try those changes & see if maybe that helps. I can
generally switch between GR37 and GR38 easily, but right now I'm doing some
GR38 CMake-related fixups & need it installed while doing so. Can't easily
switch right now ... It is very possible that setting an ID for that
Hi Chris - A few comments, more than anything else:
* You're generating 2 sinusoids then pushing them directly into the audio sink.
You're not guaranteed that the audio sink can support 2 input channels, even if
it seem to be able to. If the audio sink is working, it will always support at
Can you send me the original GRC flowgraph too? I know you modified the output
Python, but it might be useful. Also: I'm trying to use GR38 (just because) ...
so seeing what Python it generates will be useful. Thx! - MLD

Just FYI that ALSA is Linux-specific.
Chris: Did you verify that audio output is working at all on your system? If
so, then have you worked out why it's not working in your flowgraph? If not,
let us know of any changes to it since you posted last & we'll see what we can
do. - MLD

I totally agree with you, Barry: if there is an issue then show the error
always; if there is no error then don't show one. Showing it once isn't useful,
regardless of whether there was an error or not! I'll open a GR issue about
this & see if we can get some traction on it; it'll probably be a
Hi Barry - The file "gnuradio.conf" resides in "~/.gnuradio/". In my setup, I
put the "[grc]"and "xterm" lines in the file "config.conf" in the same
directory ... not sure if this is correct ... maybe I could combine them into a
single "*.conf"? Anyway ... the entry (after "[grc]") should be
Hi Wheberth - In a similar block I've created in the past, I include a
parameter, let's call it "stuffing_size", that is the number of items to stuff
when stuffing occurs. If this value is small, then there is "small" latency
between when the PDU comes in and its data is output ... but, the
Hi Al - I can't speak to PyBOMBS specifically, but the error message shows that
GMP or MPIR isn't working correctly: "/usr/include/gmpxx.h" should "#include"
the file "/usr/include/gmp.h", which should contain the function "mpf_cmp_z"

Hi Jean Pierre & Kyeong - gr-osmosdr does not have an official port to GR3.8 as
of yet. There are 3rd-party ports that might work, such as those from the issue
noted: https://osmocom.org/issues/3855 . See also:
https://github.com/igorauad/gr-osmosdr/tree/gr3.8
Hi Alex - The default OFDM Rx is fully asynchronous: It tries to detect the
packet preamble on a packet by packet basis only, without using any knowledge
of historical successful packet detection. I don't think GR provides a
synchronous receiver, and I don't know of one in any GR out of tree
FYI to any OSX user on GR3.8 :
We're actively debugging this issue, and will end up pushing a fix into GR once
the right one is confirmed. I've created a GR issue [1]; let's take the
discussion there, since in the end we'll end up with a PR & others might want
to test out the possible fixes
Hi Emmanuel - I'm the GR OSX "expert" (LOL), as I do a lot of testing and
verification and development on OSX (various versions). I'm happy to help as
best I can. It might be that your issue is a generic GR bug. Let's take this
discussion off-list & see what we can work out. If there's
Thank you, Julian ... that's the issue here I bet!
Simona is running GR 3.7.14.4, which contains a bug in gr-uhd's GRC interface
where the "set_auto_dc_offset" function is executed only if its argument is
"True". We fixed it here <
Can you execute "gnuradio-config-info -v" and report back what it returns?
Can you execute some UHD-based application (whether GNU Radio or whatever), and
report back the displayed debugging info?

OK. So did the change help for the IQ imbalance? Are you sure there is a DC
offset to be removed?
Can you provide us with a little more info: which OS & version? Which GNU Radio
& UHD versions and how installed? - MLD

Hi Simona - Since you're working in the GRC domain, you need to use variables
that make sense in Python ... "False" and "True" -- but without the ""s. "0" is
not necessarily "False", etc... try those & see what happens. Hope this is
useful! - MLD

Hi DL - One possible option that I think would handle both TDMA and FDMA and 2
streams of data: use a PFB with 2 channels (or 2 separate rotators / filters),
to create 2 parallel paths each at baseband. Each path represents complex data
that was modulated at some frequency and bandwidth & is
Hi DL - 2 primary thoughts:
1) To "create" a tagged stream block in your OOT using gr_modtool (if it
doesn't do that as you desire), find an already existing tagged_stream block
that you understand the programming of. Use gr_modtool to create a new "sync"
block, then copy/paste from the
Hi Barry - OK; good progress! Can you do the following, from the top-level
"build" directory (looks like "/home/pi/gnuradio/build"):
{{{
make clean
make VERBOSE=ON 2>&1 | tee make_out.txt
}}}
and then walk away & let it go until it's done. You'll be able to see the build
going along via the
Here are the (current) key issues:
{{{
-- Python checking for click - found
-- Python checking for click-plugins - not found
}}}
These are Python packages. If you get them installed hopefully the "cmake"
command will finish & you can get on with building from source! - MLD
