For all the GPS users out there, has anyone been able to extend
correlations to 20 ms? I have had a heck of a time extending the
correlation interval without hosing my 3rd order PLL.

Thank you for your reply, Tom.
With the 'benchmark_ofdm_tx.py' and 'benchmark_ofdm_rx.py', I receive the right
packets using the command:
$ ./benchmark_ofdm_tx.py -T A -f 2.45G -i 512
$ ./benchmark_ofdm_rx.py -R A -f 2.45G -d 256
But when I send the pre-saved file (which is saved from the
'ben
The spectrum looks clean so probably the LPF is not requirered.
I just got my hands on a USRP board and started playing with it for fun. If
I came to something interesting (i.e. complete GSM modulator) I will
contribute it to the project.
Thks again and Rgds,

Brian, Dan,
It is working now. Thanks again for your help.
One more basic "signal processing question" ... knowing that the input and
output are complex (GMSK modulated signal), should I use complex or real
coefficients for the resampler filter (rational_resampler_ccc, vs.

Hi all,
I am writting some new code to the USRP board using gnuradio and sometimes I
am getting the "uUuU" message, which I understand means that I am not
feeding the usrp.sink module fast enough (right?)
Is there a way to check what is the current CPU load?
Thank you!

Well, the receiver USRP does detect some signal, but the 'benchmark_ofdm_rx.py'
does not detect any packet.
Any ideas???

The problem is - the USRP at the receiver side does not detect anything.
