Hello Stratos,
For capturing 802.11 frames you can take a look here:
https://www.cgran.org/wiki/SPAN80211b
Unfortunately, that is just for the 802.11b standard. On the other hand,
there is one encoder developed for the 802.11g standard, here:

I would like to add that you should use four quadrant arctan, i.e. add

Thanks Marcus,
I realize I'm asking for the impossible at a certain level—"adequate but not
stellar" should be fine :)
Glad to know that the roll-off is not so steep as to make >30MHz / <50MHz
unusable as well…
Btw, I finally managed to get UDP between my external app

Just to make a note on the more theoretical aspect of this problem:
If you want to avoid all complications arising from the discontinuous
arctan, you can (and technically/theoretically you should)
work with the actual incoming signal r(t)=exp(j theta(t)) + n(t)
and its hypothesized estimate s_
Hi Josh,
Thanks a lot for the reply. The thing is, I was able to run the
benchmark_rx.py and benchmark_tx.py codes in another UHD upgraded
daughterboard. That daughter-board module is XCVR2450 transceiver.
Unfortunately, I could not run the benchmark programs in the FLEX-400
daughterboard (enabled
What frequency does the USRP1 want to see on its "ext clk" input?
10 MHz or 64 MHz?

Thanks a lot for all the replys!
Sorry that I forgot to mention I am using USRP2.
I think the link is for USRP which create a usrp group for non root control.

Hello Mario,
thank you very much for your helpful reply.
I will try to use the info you provided and infrom you about my progress.
Best,

No, it won't work. I would strongly suggest you switch to UHD. If that
isn't possible, we have some USRP2s which we can sell you.

It can accept 10 MHz and PPS from a GPSDO, but it doesn't h
One of my users in Guatemala found an issue with the build-gnuradio

Since you are only interested in RX, a loop would probably work well. You
