Hello everyone,
I have an application in which I need the USRP to track a carrier frequency
being received. What I mean by "tracking the carrier" is I need the USRP to
stay tuned to the carrier frequency even if the carrier frequency drifts (or if
the USRP's frequency reference drifts).
I was thinking that I could peridically (perhaps once per second) take the FFT,
find the frequency of the greatest magnitude, and re-tune the USRP to this
frequency.
Is there any reason why this wouldn't work, and is there a better way? It seems
to me this would be a common problem, and there would already be a good
solution, but I haven't been able to find one.
Thanks,
Thomas
