Hi,
I created a C++ block with gr_modtool,
following the commands:
$ gr_modtool newmod PWagc
$ gr_modtool add -t general power_control
I written and compiled my block with commands:
$cmake ../ && make && sudo make install && sudo ldconfig
Until this point all seems ok, but when I open gnuradio
Hi Martin,
Thank you, I got it. Those code take charge correcting phase shift
caused by CP.
The real IFO correcting is done when copy IN buff to OUT buff.
Seems there is a minor issue, if all carriers were occupied by data, OUT
buff will lose some data, right?

Very thanks for the immediate answer,
Sorry, I forgot that I passed two arguments when the block was created:
$insert valid arguments: float reference, float alpha
while "unsigned int d_counter" is a normal variable initialized in the
constructor.
now, in the file power_control_impl.h
Using predict is a similar solution to what I do in simple_ra for
"fringe stopping", except that it's all contained within the same chunk
of
Python, using a "helper" function that's tied to a every-5-seconds
polling loop. The helper function calculates the required phase
rotation, given a
Well, if all carriers are carrying data, then the signal parametrization is
bad, so this is not really an issue. That would be like leaving out the CP
and then complaining about ISI.

Make sure you're publically exporting your symbol (using the

In the other words, I want to stop top block but I don't know how? If I
have one source and one sink, I could stop the top block by returning -1
from the source, but I don't know what is the solution here when I have
multiple sources.

Hi,
I've recently installed gnuradio (3.7.2.1, through apt-get install) on
my Ubuntu 14.04.
I'd like now to build gr-baz, but cmake returns the following errors:

Hi Dimitri - I'm not sure the GR cmake files are being installed in that
version of GR. On Linux by default, these files will be installed into
"${prefix}/lib/cmake/gnuradio/", and there will be one called
"GnuradioConfig.cmake". gr-baz does not provide this specific file, and if the

Just curious, any estimate on how much temperature drift in PPM you are
getting?

Hi Michael,
Thanks for your answer. I actually tried to build the latest version
from the git repo, but it stopped at 98% with the following errors:

You should have a look at the GNU Radio wiki
