[srsran-users] About the 5GNR cell search

[Xavier Arteaga]

Hi Haoran,
First of all, I would make sure there is an NR cell nearby and that you
know its SS/PBCH center frequency of it.

Secondly, I would set the center frequency to match the SS/PBCH center
frequency.

I recommend using nr_cell_search_rf instead of nr_cell_search_test. This
one uses the SS raster for the cell search, however, it has detection
problems for moderate CFO.

Kind regards,
Xavier
