General Block Interleaver
Reorder symbols in input vector
Library
Block sublibrary of Interleaving
Description
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 (Simulink).
This block accept the following data types: int8,
uint8, int16, uint16,
int32, uint32, boolean,
single, double, and fixed-point. The output
signal inherits its data type from the input signal.
Parameters
- Permutation vector source
A selection that specifies the source of the permutation vector. The source can be either
DialogorInput port. The default value isDialog.- Permutation vector
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
Dialog.
Examples
If Permutation vector is [4;1;3;2] and the
input vector is [40;32;59;1], then the output vector is
[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 [1:4]'.
