It works for me.

"If you rebuild GNURadio with these patches, you can look at the example test_corr_and_sync.grc file, that is in that pull request, for guidance." Specifically pay attention to the 'Modulate Vector' block; which lets you specify a GNURadio modulator to run, a preamble to feed the modulator, and a post filter; used to build the sample sequence which is the matched filter sample sequence. The new correlate and sync block handles time reversal of the sample sequence you give to it. (Although it doesn't if you update the matched filter sometime later while the block is running - sorry 1 bug that was not critical enough for me to fix). The 'Modulate Vector' block might not be in mainline GNURadio, so you'll have to pick that up from that pull request too. You could always "manually" build the sample sequence for the matched filter in MatLab or Python and paste it into GNURadio as well. -Andy > > Thanks, > > Rich _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
