From my experience with QAM PHY, there are some basic debug tools to verify you
are locked on the received signal. Personally, I like the constellation plot,
it's an easy visual to see if your QAM symbols are "hitting" the right spot.
Typically you have Modulation Error Ratio, SNR etc. I
I'm having trouble with a BPSK Modulation/Demodulation flowgraph I built
(picture attached). I am using a Vector Source and a Constellation
Modulator block with a BPSK default constellation object. I'm using a
vector source because I want to verify that I can modulate and correctly

Is anyone aware of GR-IEEE802-11 having been implemented with an embedded
system? If so, what is the maximum data rate achieved?
Thanks,

IIRC, ERP is basically 802.11g. So, configure your NIC to use that.

Hi all,
I want to send data packets from my laptop to the receiver of
https://github.com/bastibl/gr-ieee802-11. How do I put my Network Interface
Card (NIC) into Extended Rate PHY (ERP) OFDM? And what will be the
subsequent process for that?
Eagerly waiting for your reply.
Thanks.

Yes. At the beginning of a a frame, the autocorrelation stays high for
some time. This makes sure
For RFNoC itself, you don't need thrift. You might just delete the
thrift line in .pybombs/recipes/gr-recipes/gnuradio.lwr and rebuild.

Hello Chris & Marcus,
Even after installing libssl-dev, the issue persist.
I am trying to install RFNoC thru pybombs, and its not going ahead at all

Also if I'm not wrong the first frame is simply discarded when the one
coming after is detected because there seems to be no provision for keeping

Hi all,
thanks to Bastian i have solved my problem. So the problem was due to zero
padding between regenerated frames as Bastian said : "The padding shouldn't
be all zeros but contain a small amount
of noise. If you send an all-zeros stream of samples, the receiver will
constantly divide by

Hi, everyone
I am using gr-ieee-80211 to recieve wifi packets on 2.4G.
The operating system is Ubuntu.The version of GNU RADIO is 3.7.5, and we use
USRP N210 with SBX daughterboard.
Our purpose:
Capture packets of 802.11 protocol on 2.4G or the other band SBX
daughterboard
Our problems:
