Path in the library: |
Description
Block BCH Decode performs BCH decoding.
The block performs the following actions:
-
Comparison of BCH bit estimates (Pbits) with channel status information (CSI).
-
Speed recovery.
-
Polar decoding.
-
CRC decoding.
-
Descrambling and splitting
24bits of the BCH transport block and8additional payload bits related to synchronization. -
Converting the last decoded bits of the BCH transport block into a MIB message.
