Hi all,
I am very new to Gnuradio and USRP, and I have a question about the code
transmission delay between USRPs.
I have two USRP E310 with UBX160 daughterboards. I send a sequence of code
from one USRP using simple amplitude modulation, and receive it by another
USRP. On the receiver side, I use
Latency is pretty normal in digital systems.
There’s buffering in Gnu Rsdio, in the kernel network and USB layers, and there
are packetizing delays.
There’s buffer in the radio and the DUC and DDC filters inherently ads group
delay.
Picoseconds? Really? EM waves in a vacuum propagate at ab
We got a new powerful Dell desktop for the lab here, and we want to put the
latest Ubuntu 21.04 on it. But will GNU Radio 3.8.3.0 build from source and
run properly on Ubuntu 21.04? Are there any known issues? Does anyone
already have this running successfully? Thanks in advance for the help, and

I am guessing you mean X310, since E310 doesn't take daughterboards. You
are seeing the effect of FIR filter delay in the USRP's halfband filters.
You can confirm this by setting the sample rate to (for instance)
200Msps/511. The use of an odd factor will result in lower filter delay but
increased
Hi Alex,
that should work flawlessly[1]. Many GNU Radio developers use Ubuntu 21.04 on a
day-to-day
basis. It's no surprise, really, though: Within one release series, Jeff takes
care that
things continue to work on the same systems! And 3.8.2.0 is what Ubuntu 21.04
ships, anyway.
Chances are
