PBCH Demodulate
PBCH demodulation.
Description
The PBCH Demodulate block allows bit estimates to be obtained for an encoded BCH block.
The block performs the following actions:
-
Uses the cell ID to identify and extract PBCH related resource elements from the received grid.
-
Uses the estimated channel and noise variance information to perform minimum mean square error equalisation.
-
Demodulates and descrambles the aligned PBCH symbols to obtain bit estimates of the encoded BCH block.
