Block interleaver

Fully parameterizable block interleaver.

This block accepts item multiples of size interleaver_indices.size() and interleaves or deinterleaves them on the output.

The idea is to define a static interleaving pattern, which is repeatedly applied to segments of the input stream. For example, if the interleaver indices are

0, 2, 3, 1

and our input is

 A, B, C, D, E, F, G, H, I, J, K, L, M

then the input is considered in segments of the same length as the interleaver index vector:

 A, B, C, D, E, F, G, H, I, J, K, L, M, …
|––––––––––||––––––––––||––––––––––||––÷
 0, 1, 2, 3  0, 1, 2, 3  0, 1, 2, 3  0, …

which are then individually permuted according to the index vector

 0, 2, 3, 1  0, 2, 3, 1  0, 2, 3, 1  0, …
|––––––––––||––––––––––||––––––––––||––÷
 A, C, D, B, E, G, H, F, I, K, L, J, M, …

Parameters

(R): Run-time adjustable

IO Type

type of the in- and output streams

options: [byte, complex, float, int, short]

Interleaver indices

indices of items in output vector

default: '[1, 2, 0]'

Mode

switch between interleaverand deinterleaver mode
