Hello, I am doing research where we are trying to implement TCP through
gnuradio and USRP B210s. We want to use OFDM, so I have modified the
ofdm_rx and ofdm_tx examples into one large graph with a TUN/TAP interface
and USRP source/sink. Currently, I have the graph running on two separate

This is a problem I have faced as well. I have a number of projects at
various levels of modification of GR and various 3rd party python packages
being supported. I find having virtualenvs to be very useful in keeping
python package versions, GR mods, and my own modules in agreement. I've

Hi everyone,
I'm trying to develop a packet-based, single-carrier system (BPSK, QPSK,
QAM) with FEC (CC) similar to that implemented in packet_rx.grc and
packet_tx.grc. I am using two Ettus B205mini-i as my USRP devices,
connected for now, via a 50Ω, 30dB attenuator and SMA cable (antennas also

You can see opensuse Thrift here:

If you poke around the page, you will see 0.9.3 is the most recent rev.
So I'm not sure what else I can do.
But if there is something else related, I can update it. Also if you

Dear Annie,
I'm sure you'll find the answer to that when you read through
frame_equalizer_impl.cc and look for 4-tuples of vector indices that
look like the indices of the pilot tone carriers in OFDM.
Best regards,

Hi,
Are pilot tones used at all for equalization in wifi_rx ? I do not see that
being done in the WiFi frame equalizer block. Also even when I change the
amplitude and phase of the pilots in Wifi_tx other than the default 1, the
WiFi packets were still being decoded correctly. Is it because that t
Hi Lazygranch,
well, good news is that it's really just ctrlport. If you don't care
about that: it's not even going to crash anything at runtime, as far as
I can tell. You just won't be able to use ctrlport.
If you do care:
So, ctrlport is our RPC framework, with which you can control GNU Radio
Hi Emanuel,
you can technically do that, pass a python object (if you write your
block in python) or a smart_ptr as a parameter to a
method or the constructor of your block (in C++).
However, that feels like it'd be wildly ugly in terms of "who owns
what"; it might be the best way, still. If you
Hi Nikita,
that would sound like you'd need to implement it yourself – and put a
lot of thought into how you can make a display that manages to show a
(potentially infinite) amount of data on a limited display; probably
something like downsampling or only storing the min/max for periods in

GNU Radio releases 3.7.11 and 3.7.10.2 are now available for download.
Release 3.7.11 is the latest of the 3.7 API, with new features, and
includes all bug fixes in release 3.7.10.2.
Both releases and their detached signatures are available via the following

Thanks Julian, I think this should do it for now. In fact, it is quite
relevant to what I trying to do.
Also Marcus what should I do if I don't want a "paper ticker" but utility
which as you say "constantly rescales" the display?

Hi all,
Do you know if the following is possible in a flowgraph:
1. I have a USRP sink instantiated and configured in GRC
2. I have my own OOT block from which I want to get the current time of
the USRP sink. Independent of the fact that the sink is streaming or bursting

Hey,
if you are thinking of something like a "paper ticker" like Marcus
mentioned, you could take a look at

that roll in from right to left.
This could probably be done in a more easy way using the existing QT Gui

Hi Nikita,
so, you'd be constantly rescaling the display, or are you more thinking
of something like a "paper ticker" thing, where new signal "slowly"
pushes out old signal?

Hello everyone!
I have an application where the end result is a numeric value that keeps
changing with time as the variables change during runtime.
I would like to plot these values on the time axis much like QT Time sink
does for the entire duration of the GNURadio simulation. This means that

I'm trying to build gr-cdma in Ubuntu 16.04 following the instructions in

I can build it with

But when I enable doxygen it fails. I have installed

Hi Andy,
What can I say, this is amazing... I need to digest this a bit again
and Im currently working on some hardware bits. Hope to get this
flying in the next week or two. Will let you know how it goes.
