Hi Bastian,
Now the grc examples work with no error. The crash of the system during
gnuradio compilation is due to the boost version (the version 1.46 causes
the problem). After I switched to version 1.48, the compilation of the

Hi Bastian,
I am using Ubuntu 12.04. I first try to compile the gnuradio with
build-gnuradio script. But the system crashed after starting making
gnuradio.
So later I use the precompiled gnuradio and uhd directly from ettus. It
seems that the gnuradio is install in the folder
/usr/local/lib/pytho

Hi Bastian,
I am newbie to USRP and Gnuradio. I did make and make install of your
project. But when I opened the rx.grc, I got some errors. Could you please
take a look what is the cause for that?
Thanks in advance.

interested.
The changes are:
- It has a transceiver flow graph. (That was really easy with the new
PDU to tagged stream block)
- annotate LQI value in dict of PDUs
- CRC check
