Hi all,
we're having our last project call of the year this Thursday, at 10:00
AM Pacific time, 19:00 CET, 1800 UTC.
To join the call go here: https://meet.jit.si/gr-call
Also, join us on IRC or Slack. There should also be a YouTube stream
available, but let us figure that out. All this

This is phase modulation of a carrier. You can implement it by multiplying

Hello Marcus,
yes I have been reading gnuradio tutorials all day long maybe 14 days, but it
is really hard to get into it.
I am now trying to combine:
signal_source + stream_to_tagged_stream
and
constant source (const = 0) + stream_to_tagged_stream
If i put that into tagged stream mux I have
Hi Guy,
I've had these issues when linking to libraries.
Go to the CMakeLists.txt in the root of your OOT module, and look for the
line find_package(Boost..
Make sure you include chrono in your components list, i.e.:
find_package(Boost "1.35" COMPONENTS filesystem system *chrono*)
After
Hello Petr!
Well, OK, so what's that got to do with the Wifi in your subject?
In any case, we do have Constellation Encoder, and Patterned
Interleaver. These two blocks might make the center of your
application.
Have you already been pointed towards the Guided GNU Radio tutorials?

That usually happens if python can't import the created module.
It can have several reasons why it can't:
1. the installed module is not in your (custom) PYTHONPATH
2. The python module tries to import the C++ code
Guy,
I assume that error is coming from Python. If that's the case, then
it might be that your Swig build messed up somewhere or the lib and Swig
are not agreeing. When I get those kinds of errors I will edit the
__init__.py file for the Python module (likely in
Hello,
We are trying to take control over drone.
The drone starts for example at 2,4 GHz and has some pulse width, and pulse
repetition frequency we know.
Pulse1: at start of pulse there is 2,4GHz carrier to synchronize and then BSPK
data (two numbers in binary)
Pulse2: carrier 2,4GHz + BPSK
Hello,
The purpose of my study is the effect of (mechanical) vibrations of an
antenna on the signal.
So let begin easy and let's say that a signal without antenna vibration is
x(t) = a*sin(w1t)
Now if the antenna is vibrating, the signal becomes
x(t) = a*sin(w1t + deltaphi*sin(w2t))
With the
Hi Horký,
could you give us a bit more context? The signal you're describing
sounds like a single-carrier system, but (modern) WiFi is an OFDM
system, so I'm not sure what you really want to achieve?
Maybe paint the bigger picture of why you need this!
Best regards,
Marcus

Hi,
I am developing some kind of MAC layer within a GNUradio model. Until
now, my C++ mac module works.
Now I need to add time functionnalities to my module. I include the
following declarations:
---
boost::chrono::system_clock::time_point now =
boost::chrono::system_clock::now() ;
Hello guys,
my task is to create pulses with half period carrier/ half period bpsk in it.
After two pulses I hop to another frequency. Is it possible to create this with
only blocks, or I have to write the code myself.
Can you give me your ideas how would you do that? Is using stream tags the
Hello everyone,
I created an OOT block,decoder, using gr-modtool but I get the following
Attribute error when I run my flowgraph. I guess there is a problem with
the external libraries linking against to the implementation.
