Sorry about previously. I guess I need to read more :). I got the
gdb backtrace.

Hi All,
For the OFDM, the fft_length is the total number of subcarriers, and the
occupied_tones is the total number of subcarriers that carry actual data,
which are in the middle of total subcarriers. However, I want to make the
subcarriers randomly on or off, which means, the occupied_tones ar

Hi All,
I'm using Ubuntu8.04 and trunk version 10200. After installation, I tried to
run ./usrp_benchmark_usb.py. However, I got the error like this:
Traceback (most recent call last):

I can see that will cause the flow graph to hang. And I followed your
explanation.
I have added a "timeout" feature to block D, so that after
Hi All,
i am trying to create an AM Radio with Gnu-Radio-Companion,
therefore i need some help.
Maybe someone still worked out some AM Radio with
Gnu-Radio-Companion, then please send me your
Companion File.
If so, it would be nice if this Person do some Notes.
Further on i have some Questions

Hi All,
I am trying to install gnuradio from trunk (svn co

from boost.sourceforge.net, and install boost_1_36_0 first.

No, not OK.

But this isn't happening in my scenario. If necessary, I can add an event
timeout or maximum size event value to prevent this
Hi everyone
I have searched around for this information, but am having a tough time
finding it. I am trying to do 64QAM soft symbol to bit conversion in
gnu radio. It would be something similar to gr.binary_slicer_fb, but
work on complex data and output binary data.
Is there anything like this
Sorry my ignorance, I revised my question and i was not clearly...
There is a condition on line 1008 in usrp_standard.cc code. That condition
limits the LO frequency (see my schematic) to the maximum of 44 MHz, OK? But
you can read in the mailing list that the baseband frequency is limited to 4

Hi
I'm trying to debug an application using gdb. I used the segment of
code in the how to write your own blocks page to print out the process
id and attach gdb to it. When I try to set breakpoints, I get a
message saying
No line 110 in file ''../Modules/python.c''
Also, when I run the Python a
