Layer Mapping
Codeword Mapping.
Description
The Layer Mapping block performs the mapping of a codeword (or codewords, depending on the value of the Number of code words parameter) to transmission layers according to the specification in accordance with [1], sections 6.3.1.3 and 7.3.1.3. The block returns a matrix with modulation symbols distributed over transmission layers, where the rows are modulation symbols and the columns are transmission layers.

Details
Number of transmission layers:
-
If the Number of code words parameter is set to
1, the Number of transmission layers must be from1to4. -
If the Number of code words parameter is set to
2, the Number of transmission layers shall be from4to5.
The length of the input word must be a multiple of the number of layers.
