Edwin,
can you share some details on the receiver code you're using?

Dear Ruediger:
(Actually, you probably don't have to double-check $PATH as suggested in
step 4, since 'whereis gnuradio' should locate these files for you..)

Dear Ruediger:
It could be somewhat tedious, but could you try this?
1. remove GNU Radio installations again (using apt).
2. type in "whereis gnuradio" -> if you found any remaining GNU Radio
files, remove them.
3. type in "whereis gnuradio-companion" -> if you found any remaining GNU
Radio file
... I went to the build directory generated by the build-gnuradio script
and uninstalled using "make uninstall". I then used apt-get uninstall
gnuradio to remove the package installed with apt-get. As a final step I
reinstalled with apt-get install. Unfortunately gnuradio-companion is
now not s
Dear Ruediger:
Could you try removing all GNU Radio installations except one (that you
would use), reboot the system, and then re-build -> re-execute the code?
Because I have seen a case where multiple installations of GNU Radio messed
up the PATH variable and caused a similar issue..

Dear Marcus and Kyeong Su Shin
indeed I used the build-gnuradio script before I installed gnuradio by
apt-get. Sorry for not having mentioned that and in fact I did not
deinstall after build-gnuradio.
Thank you,
Ruedi

Dear Ruedi,
I am pretty sure that Ubuntu 14.04 does not come with GNU Radio 3.7.11.1,
so you cannot simply apt-get it from the official repo. Did you add a PPA
or use any other installation methods by any chance? If so, did you remove
the previous version of GNU Radio (if you installed it before)
Hm, ok, I was hoping for some parser problems within GRC to produce
errorneous configuration of your QT GUI Frequency sink, but nooope.
Exactly, byte-wise, the same file as mine.
S, there's something crashing in Qt GUI.
So, how did you get 3.7.11.1 on Ubuntu 14.04? you say apt-get, but

Hi Adhitha,
The tx_stage6.grc outputs BPSK packets. If you want to use OFDM, the OFDM
examples are good references. To detect OFDM packets, use schmidl & cox
OFDM sync module. Anyway, I'm glad that you've got your system going.
Regards,
Edwin

Hi philip,
to identify such bottlenecks, it's often a nice clue to know which block
consumes the most CPU. I don't know it the Linux perf counters work well
on ARM (simply haven't tried), but if they do: There's a program called
perf. Usage in short
sudo sysctl kernel.perf_event_paranoid=-1
perf
Oops, should have read the *11th* of August (tomorrow).
Thanks, Marcus, for pointing out my typo!
Cheers,

Hello,
I'm using gnuradio-companion 3.7.11.1 installed using apt-get on Ubuntu
14.04.5 LTS running on a Lenovo T60.
The dialtone example works fine but once I'm using the frequency sink
like e.g. in the resampler_demo.grc I get the following Runtime Error:
Generating: '/tmp/resampler_demo.p
Hi all -
This is a heads-up that our negotiated room rate (which matches the US
Federal Government's per-diem rate for San Diego) and room block is no
longer guaranteed by the hotel as of EOB this Friday, the 10th of August.
If you haven't yet booked your rooms for GRCon, please do so soon!
