In my experience, there seem to be endless permutations of problems

For the majority of my tests (ex. below), with benchmark_ofdm_*, the

Hello everyone,
I am a postgraduate student at Technical University of Crete, Chania
and i am currently working on a project with USRPs. Part of our
project is to communicate with a relay node. But this relay node is a

Hello everyone,
I have posted a similar question before but didnt get too much attention
thats why I am posting this question with hopes that I will get some
response this time because I have tried to make the question simpler.
In one line the problem is I am so far unable to configure 2 RX
Hi,
I never used Gnuradio packets transmission blocks and even don't know how
the digital benchmark_?X.py work. But, today when I was explaining GNURadio
for some friends, I noticed that some digital modulations (for example GMSK)
reception can be improved by using a scrambling engine which is

GNU Radio has gr.scrambler() and gr.descrambler() blocks to
do this.
In the example digital packet radio application, we instead use a
whitener that has a pre-generated sequence of bits that we XOR the
payload with.
Hi,
I am trying to use benchmark_ofdm_tx.py and benchmark_ofdm_rx.py to test the
OFDM communication between two usrp nodes.
While the transmitter is sending data, I use a sprctrum analyzer to observe
the spectrum, and find the signal bandwidth far beyond my calculation, which
is 330kHz around
What is the situation with VRT and UDP? Has what's going into the VRT
context packets been finalized? If so, where should I look for this
information? I've been looking in Eric Blossom's branch, it looks like he
is doing most of the VRT development, is this right?
Who is doing the UDP
This sort of thing is heavily dependent upon the transmission environment. I
wouldn't think it could be generalized.

We've got UDP and the IF-Data working on an experimental platform, but
it hasn't been ported to the USRP2 yet. When everything is fully
wrung out on the experimental platform, we'll back-port it
my audio sampling rate is 48000 not 32000 so all the the gnu examples that
output an audio dont work and due to this 48000 i cant configure the decimation
and interpolation to be even integers as required
so is there away to change sampling rate of my audio card to 32000
