Hello guys,
I'm getting some problems to use the error rate on a ofdm system, i used the

there's not any response, it doesn't bring me any error but the results are

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

Ok, to be completely frank here:
It looks like your computer is not up to the task of mixing pulse
streams while simultaneously doing signal processing and watching

I tried rebuilding gr-air-modes with make -j1 both for build and

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

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
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.

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
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,

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.
