Hi everyone,
In prep for GR 3.8 I noticed the fast auto-correlator sink in gr-baz is still in WX GUI last time I used it, so I ported it over to use QT GUI instead and added an option for current (dB) or normalized output. There's also a new fast auto-correlator block in the OOT module that outputs the results as a vector (rather than the UI sink) for other downstream processing with the results.
The blocks are in gr-mesa (
https://github.com/ghostop14/gr-mesa.git). I haven't ported gr-mesa to 3.8 yet but after the working groups at GRCon I'll split it into the 3.7 maint and 3.8 master branches so we'll have a 3.8-compatible version.
