Hi Johnathan,
can you suggest me a place where I can find more information about the phase
sync and the freq sync methods you used in your work. It will be of great
help to me.
Thanks,
Ali.

D'oh! Took me long enough to notice that the optfir block generates
coefficients, but isn't the filter itself. Putting it into the pipeline
directly was a bad idea.
So I have transmitter and receiver, and they run without errors... they just
aren't giving me what I expect. The filtered sum of sin

Hello All,
I am trying to capture the communications between a RFID reader and an EPC
Gen 2 tag (920 MHz). I tapped directly into the antenna of a Thinkmagic M5e
RFID reader. I turn it on and it starts reading the tags. When I look at
the raw signal from the usrp or an Agilent signal analyzer,
Are you using the ThingMagic in monostatic mode (one antenna that does
RX and TX)? If so, you probably won't be able to see the tag reply.
Further down the receive path the ThingMagic has circuitry that
removes the strong TX signal leaving only the tag reply, but I assume
you are tapped in before t
Hello!
I'm running GNURadio/OpenBTS with Ubuntu Linux and an external clock
with 64MHz.
Now I want to use an external oscillator with 10MHz.
Is it possible to run the USRP and the daughterboards (RFX1800) with
this frequency?
I read the article about Clocking

I wrote some lines for people asking for help in the wiki [1]. For the
old stagers, please look through it, it can certainly need some
polishing. Especially the common-mistakes section could need some more
examples.

Stefan--THANKS for all the wonderful work you've been submitting; we
really appreciate the kinds of optimization work you are doing. We
will likely get all of it into our distribution.

Hi,
I've added a few changes to the IEEE 802.15.4 *TX path* in UCLA_ZigBee_PHY

using cc2420_txtest.py on one computer and cc2420_txtest.py on another
