Random Interleaver - Reorder input symbols using random permutation

Library

Block sublibrary of Interleaving

Description

The Random Interleaver block rearranges the elements of its input vector using a random permutation. The Number of elements parameter indicates how many numbers are in the input vector. If the input is frame-based, then it must be a column vector.

The block can accept the data types int8, uint8, int16, uint16, int32, uint32, boolean, single, double, and fixed-point. The data type of this output will be the same as that of the input signal.

The Initial seed parameter initializes the random number generator that the block uses to determine the permutation. The block is predictable for a given seed, but different seeds produce different permutations.
