How to capture the PN_Peak value in preamble before normalization during sync in OFDM?

Hi guys,

Did anyone know how to print out the PN_peak value in preamble after
correlation but before normalization process? The sync file is
*ofdm_sync_pn.py.
*But I have no idea which block should I modify? Thanks so much

Best,
Kay.

You can add one “gr.probe_signal_x” in the sync block after the
correlator and call “sync_pn.probe.level()” in the receiver whenever
needed.
