Hi everybody,
I have been trying to design a ionosonde with USRPsin my final year
project.
I am responsible for the signal processing part of the project. I will
have been
using USRP1 untill hardware part, that is amplifier and antennas, is set
up.
I have been using another USRP1 & a PC to model an HF channel, and
processing
the delayed signal in my own PC. As far as I see in web site of Ettus
Research,
http://files.ettus.com/uhd_docs/manual/html/usrp1.html, and several
similar
projects completed USRP2s are better to use for such a purpose.
In processing of the received signal, the peak of the result of the
x-correlation
must not even be different from the its actual instant as three micro
seconds.
That is why, I need to make sure if Tx and Rx starts working at the same
instant
and perfectly synchronized, in other words , if they perform parallelly
at all?
Thanks in advance,
Abdullah
