Make sure both your radios are locked to the same clock source.
Any fsignificant requency offset between the two is going to ruin your
correlation peaks very quickly.
Frequency offset is going to end
Hi all,
I am trying to measure the distance between two BladeRFs by comparing the
phase of a pseudorandom (PN) code in GNU Radio Companion. Radio 1 streams
the code (+/- 1s, so BPSK) on one frequency, Radio 2 just retransmits it on
a different frequency. Radio 1 receives that delayed code. An FIR
Hi Manuel,
I haven't taken a very detailed look at your flowgraph (the symbol rate
being 10e6 with a sampling rate of 400kHz seems odd), but:
* 400kHz sampling rate means that the complex baseband you get out of
your USRP represents but 400kHz of bandwidth. Your let's have a look
at you
Remember: signals moves at rough 3.3 microseconds per km...
