SSS search
SSS Search.
Description
The block extracts SSS-related resource elements from the received demodulated signal and maps them to each possible locally generated SSS sequence. The indices of the strongest PSS and SSS sequences combine to give the physical layer cell identifier that is required for processing the PBCH DM-RS and PBCH.
The block performs the following actions:
-
Extracts the received SSS symbols from the SS/PBCH block.
-
Matches the received SSS characters with each possible SSS sequence.
-
Determines NID1 by finding the strongest correlation.
-
Forms an overall cell identification based on the evaluated NID1 and NID2.
