Description
Block SSS search extracts SSS-related resource elements from the received demodulated signal and correlates them with each possible locally generated SSS sequence. The indexes of the strongest PSS and SSS sequences together give the physical layer cell identifier, which is necessary for processing PBCH DM-RS and PBCH.
The block performs the following actions:
-
Extracts the received SSS characters from the SS/PBCH block.
-
Matches the received SSS characters with each possible SSS sequence.
-
Determines NID1 by finding the strongest correlation.
-
Generates a general cell identification based on the estimated NID1 and NID2.
