Is there any PN cross correlator implementation for packet detection in Gnuradio?

GNU Radio

Hi guys,

I noticed that Gnuradio uses schmidl PN correlator for packet detection
by
defalt, where the 1st copy autocorrelate with 2nd copy in one preamble.

I wonder if any PN cross correlator is implemented, which means the
received signal is cross correlated with known preamble stored locally.
Thank you so much.

Best,
Kay

You can either use an FIR (see the filter section) or one of the
correlators from the ‘Synchronization’ section.
