Dears,
I am working on GNURadio flowgraph where I use a Tag Debug block
(https://wiki.gnuradio.org/index.php/Tag_Debug).
In my grc-graph, the output of Tag debug is displayed on the command window as
(I,Q) tuples.
Can I save the output of the Tag debug displayed on the command into a cvs file?
Dears,
I am doing some analysis on channel state information of OFDM signals. I used
GNURadion rx_ofdm.grc (gnuradio/gr-digital/examples/ofdm at main ·
gnuradio/gnuradio) for signal transmission and reception through a channel
model block. Then, the CSI has been extracted using Tag debug block
Hello,
I am utilizing two USRPs, specifically the X300 models, along with GNURadio
for the purpose of transmitting and receiving OFDM signals. I have implemented
the OFDM flowgraphs available on Github for this purpose. The transmission and
reception setup involves LOS (Line-of-Sight) configur
clock source to "external".
Also, good idea to isolate multipath effects, but don't forget that if your
system can't deal with the multipath environment you're in, you've incorrectly
designed your OFDM system.
Best,
Marcus

overdriving the receiver and causing
distortion errors.

- any unfortunate condition in your receiver chain
may also affect your reception.
The questions that arise are:
- What do you want to fix here?
- Did you observe anything that you didn't expect?
Cheers

Hello Dears,
I would like to inquire about the synchronization of two USRPs X300, one
acting as a transmitter (Tx) and the other as a receiver (Rx). If both USRPs
are connected to the same laptop, I'm wondering if the accuracy provided by PC
clock synchronization is similar (or close) to that

No, it's several orders of magnitude worse and generally insufficient for
anything where you need synchronization.

Any OFDM receiver needs a timing recovery method anyways, so that has nothing
to do with
how well your PC is suitable for synchronizing two devices.

So, I have to get GPS modules and use GPSDO synchronization.
