Hello,
I just created my first 2-level FSK demodulator and
would like to add carrier-tracking to find the carrier
frequency. Since some RF signals are offset by about
5kHz. I need a way to zero in on the frequency to
compensate for the offset. Is there a block that
performs this function? Or,

I suspect you mean the FPGA on the usrp.

Hi Kevin,
I think the capabilities that we are developing at the moment are
related. What we soon hope to achieve is a USRP server (Linux box
running GNU Radio with a USRP), servicing clients (only one at this
stage) that are running Windows/Matlab. Communications occur over
TCP/IP. The serve
I'm starting to work out some test code regarding the host end, and I was wondering how
hard it will be when done testing to actually put a packet on the bus? I assume we can
reuse some of the previous interface.
Question from Thibaud: is the loopback interface working on the USRP, and how

Hello,
Is anyone of you working fulltime with the FPGA? I want to ask a few
questions.
Because I hardly find any documentation on GnuWiki on that or I hardly get
any replies to my posts on the FPGA.
Thanks a lot.

Hi, my friends.
Our 2 x 2 MIMO-OFDM system is nearly acomplished. I'm glad to share some
details about it later.
Now I'm starting to working on a 4 x 4 one. Of course it'll needs two clock
locked USRP , 4 tx db and 4 rx db. We're using rfx2400.
