Description

Block General Block Interleaver rearranges the elements of the input vector without repeating or skipping a single element. If the input vector contains elements, then the parameter Permutation vector represents a column vector of length . The column vector indicates the order of the indices of the input elements that form the output vector of length That is ,

Exit ( ) = Input (Permutation vector( ))

for each integer between 1 and . Parameter Permutation vector must consist of integers from 1 before without repetition.

Input data and parameter Permutation vector should represent column vectors.

Example

If the parameter Permutation vector It matters [4,1,3,2], and the input vector is — [40,32,59,1], then the output vector will have the value [1,40,59,32]. Note that all these vectors have the same length and Permutation vector contains integer values from 1 before 4.
