Thanks Marcus for the explanation. Yes, we take care
of attenuating the signal along the RF-cable.
Can you explain bit more
"So the best approach is to simply set a bit in your application for your
RX chain to simply ignore the RX samples while you're transmitting".
can this be done in the python layer or do I have to touch the c++
layer? I am using ofdm as the physical layer (ofdm.py etc.).
Sorry, if all this sounds incoherent; I am still a newbee in this
field.
thanks and regards

Well, assuming you have TX thread and an RX thread, you can signal to
the RX thread, via a shared variable, or some such,
that TX is currently in progress, and to please ignore any samples
for a while, or some such thing.
I'll make the general comment that nobody can be really successful in
SDR, if the 'S' part of it is a bit of a mystery to them.
Real-world signal-processing solutions require things beyond the
strictly-mathematical treatments of DSP you find in textbooks.
In real systems, you need to implement algorithms that aren't
strictly-mathematical in nature, and require some non-trivial
understanding of familiar topics in CS and computer-programming
concepts.
