Reorder symbols in input vector
Block sublibrary of Interleaving
The General Block Interleaver block rearranges the elements of its input vector without repeating or omitting any elements. If the input contains N elements, then the Permutation vector parameter is a column vector of length N. The column vector indicates the indices, in order, of the input elements that form the length-N output vector; that is,
Output(k) = Input(Permutation vector(k))
for each integer k between 1 and N. The contents of Permutation vector must be integers between 1 and N, and must have no repetitions.
Both the input and the Permutation vector parameter must be column vector signals.
This block can output sequences that vary in length during simulation. For more information about sequences that vary in length, or variable-size signals, see Variable-Size Signal Basics in the Simulink® documentation.
This block accept the following data types:
and fixed-point. The output signal inherits its data type from the
A selection that specifies the source of the permutation vector.
The source can be either
port. The default value is
A vector of length N that lists the indices of the output elements
that came from the input vector. This parameter is available only
when Permutation vector source is set to
If Permutation vector is
the input vector is
[40;32;59;1], then the output
[1;40;59;32]. Notice that all of these
vectors have the same length and that the vector Permutation
vector is a permutation of the vector
