Dear user,
I think this is not the way to implement OFDM simulation. It requires
multiply const block before channel model. You may get variation in BER
value when you use USRP boards. I will execute the same flow-graph and let
me inform you results in soon.

Hello
Problem solved. I removed the QApplication() from the example. Matplotlib
was used for plotting, no need of qApp!!
Thanks

Hello All,
I am working on learning gnuradio and getting a grip on demodulating
digital communications. I've been a ham for a long time, and this seems
far from my days as a kid running 1200 baud half duplex AFSK. ;)
What I have is a toy with a cc1101 chip in it that transmits @ 19.2 k baud,

I'm looking for some tips on how to improve file transfer using two USRP's.
I understand the method I'm using might be fairly crude, but I'm just
starting out.
Problem is I'm dropping a lot of data out of the file (receiving missing
parts of a string and such). This gets really bad when one of the
Connect up a null sink and null source in parallel with the uhd blocks. Then
right- mouse on the uhd blocks and select "disable". This will gray-out the
blocks and not compile them, but will leave them there preserving all your
parameters.

Miklos and Tom,
one option may be to merge the work that Miklos described with gr-trellis
(or the other way around :-))
Recall there was a discussion in the recent past of volk-ing the basic
trellis algorithms such as VA and SISO.
I believe the work that Miklos describes would be a wonderful way t
Thanks.

Hello GR,
Are there any fake sink and source blocks which simulates the uhd sink and
source.
I would like to test some flow graphs but for the moment I don't have access
to the radios.
Or is there any other option, let's say using a channel block between the Tx
and the Rx.
Any hints or explanati

The BER results are wrong, it gives me a value of "0.0 Units" always

I tried rebuilding gr-air-modes with make -j1 both for build and
install, but it did no help. I even changed the generic makewidth
setting to 1 and rebuilt gnuradio, rtl_sdr..., but the problem is still
there.

Hi
I am trying to figure out how to use smith chart as a sink in GNU Radio.
I made an OOT (https://github.com/mitul93/gr-smithchart) using pyQT by
following Tim O'shea's work.
It is merely a skeleton, still lots of work to do.
I made two versions of smith chart - one using pyQT and another using
