Correlation Estimator

GNU Radio
1

Was the Correlation Estimator block recently added? If so, thank you
whoever wrote it. If not, thanks anyway. It seems to be an alternative
to
the infamous Corr_and_Sync block.

I also like the testbench that goes with it in
gr-digital/examples/demod. I
did not know I could use Modulate Vector (or the existence thereof) to
pre-modulate a preamble. Very clean.

Just some positive feedback.

v/r,
Rich

Both corr_est_cc and modulate_vector were written and contributed to GNU
Radio by Nick F. and Andy W., and are intended as a more general
replacement for corr_and_sync, and were recently merged into master for
eventual release in 3.7.8.

Tom R., Sean Nowlan, and I are working on better packet/burst mode
processing and the above is a nice addition to that.

The modulate_vector function/block may undergo some changes as we’re
trying
to figure out the best way to deal with group delay in the pulse shaping
filter.

I appreciate everyones work. It’s making my job easier.
