[Discuss-gnuradio] Distance Measurement by Correlation

2019-02-25 Thread Jonathan Preheim
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
