Hi all,
I have a question about the decimation rate of GSM (channel is 200kHz wide).
I search the decimation rate of GSM for GNURadio on the Google. I got some
information from

However, I don't understand why
Hi

I'm baffled. I formatted the SD card and made sure the USRP2 didn't
boot up (No LEDs lit). Then reflashed it with the latest firmware and
FPGA image (2 LEDs lit). I still see 0.0 Q samples at 2.4G, 2.45G etc.
I've tried swapping the RFX 2400 daughterboard with a spare AND two

Hi,
I was taking a look at the ofdm files by using first the benchmark
with log enabled and then the plot.
First I copied ofdm_frame_sink_c.dat to ofdm_frame_acq_c.dat because
this last file was missing.
I would like to have some comments about the resulting plot I had :

There is a problem with the installed version of python-lxml package. My
machine has lxml version 2.1.1. The latest version of lxml is 2.1.5
(http://codespeak.net/lxml/index.html#download).
Perhaps you have a very old version of lxml that is missing some feature

I installed Ubuntu 8.10 the way described on the GNURadio website and
it works.
No idea why the last installation didn't work. The only difference
was, that I built it your way (but this should't be the problem).
Anyway, thank you very much. I see spectrums, oscillat

Eric,
Yes, I have looked at that header file. I wrote a small program to
try using the usrp2 class and tried to compile it without success.
Code usrp_demo.cc:
#include
int main()

const char *interface = "eth0";
const char *mac_addr_str = "00:05:2c:85:30:a7";

Thanks for your reply Bruhtesfa, by subtracting the log of the FFT size, I
