I was super curious about the signal you posted so I ran it through MATLAB a little. Here is the time domain `(10 * log10(abs(samples).^2))` of one of the bursts...

If you'd like to try it yourself here's the MATLAB script (dunno if it will work with Octave). Make sure to change the path to the collect. Also, I used...

@lobart that last image you posed looks like DroneID. Did that work with the Octave/MATLAB? The other images you posted do not look like DroneID.

@lobart That's not terribly surprising. The GNU Radio code is not up to date with the MATLAB (from the `main` repo). The equalization is atrocious, and the integer frequency offset...

I never followed up on this, but I found a way to do integer frequency offset detection that works with my HackRF (thanks @MAVProxyUser!). The code is currently only in...

The rewrite branch will use the updated integer frequency offset code. One day I'll get back to work on that branch :\

I'm not sure I quite follow the question. It sounds like you recorded samples with the file sink in GNU Radio and then processed those samples with the `process_file.m` script....

Apologies for the delayed response. I don't know if that drone supports DroneID. The message you sent me hints that the correlation scores are very low which likely means that...

You cannot use the PlutoSDR for capturing DJI DroneID signals as the PlutoSDR is not able to capture signals over about ~ 4 MSPS (in this case equivalent to ~...

It does look correct in terms of number of OFDM symbols and location/structure of the ZC sequences. I can't tell if the sample rate is correct from the image though,...
