codeblk = lteBCH(enb,trblk)
a vector of BCH transport channel coded bits. The encoding process
includes CRC calculation and attachment, convolutional encoding, and
rate matching as defined in TS 36.212 , Section 5.3.1.
codeblk = lteBCH(
The rate matching internal to the coding results in many repetitions of the coded block. This repetition is deliberate so that part of a received block can be successfully decoded in isolation. Typically, the receiver can recover the BCH bits from the reception of just one frame (¼ of the transmitted block), rather than waiting 40 ms (four frames) for the full block to be received.
enb— eNodeB cell-wide settingsscalar structure
eNodeB cell-wide settings, specified as a structure that can contain these parameter fields.
|Parameter Field||Required or Optional||Values||Description|
1, 2, 4
Number of cell-specific reference signal (CRS) antenna ports
Cyclic prefix length
trblk— Transport blocknumeric vector
Transport block, specified as a numeric vector of length 24 bits. This argument represents the transport block delivered to the BCH every 40 ms.
