Hi,
My research group is in the process of exploring about the purchase
of USRP2 which employs SPARTAN-3-2000. In this regard, I had a few
queries:
1. Is there some room leftover on the SPARTAN-3-2000 for USRP programming? -
Many people whom I contacted were of the opinion that there is

I believe that gnuradio.org is down right now. I have put a mirror of
the latest git master on github.com for those who need to get at it
quickly. You can clone using:
git clone git://github.com/yootis/gnuradio-matt.git

Running through a descrambler and then trying to correlate with 128 ones, I

There are clearly 11 spikes, but the closest we get in a window of 128 bits,
is roughly 82 ones. Here a

That's probably ok. I haven't ever used one of the breakout cables to
connect to a SATA connector, but it sounds like SATA cables don't have
the built in crossover like the SAS ones do.

Thank you for the fast reply. It looks like I need the SATA fanout
connectors to be the host in this case because pin 2-3 are TX for the
SATA port. Would there be any issue having the mini-SAS as the target?

Hi Ben,
I was having problems with what appears to be blocks of data being saved out
of sync (tended to happen at decimation rates lower than 100) but I haven't
had a chance to get to the root of this issue, my current line of thinking
is that when blocks have a side effect the ordering isnt guare

I managed to get rid of problems. I just deleted the gnuradio
libraries and headers from /usr/lib/python2.6/gnuradio, /usr/lib and

I double checked the scrambler code and I really do not see anything wrong

Hi all,
I've been trying to build BBN 802.11b code (USRP2 version) from CGRAN,
but I haven't had success. I have a problem with Python (2.6) importing
libraries from bbn_80211b_pkt. I've run ./bootstrap, ./configure, make
and make install in the folder bbn_80211/usrp2_version.
