PBCH Demodulate

Demodulation of PBCH.

blockType: PBCHDemodulate

Path in the library:

/5G/PBCH Demodulate

Description

Block PBCH Demodulate allows you to get estimates of the bits for the encoded BCH block.

The block performs the following actions:

Uses the cell identifier to identify and extract PBCH-related resource items from the accepted grid.
Uses estimated information about the channel and the noise variance to perform an equalization to a minimum of the mean square of the error.
Demodulates and descrambles aligned PBCH characters to obtain bit estimates of the encoded BCH block.
