Matrix Interleaver

This block performs interleaving by filling a fixed size matrix row by row and then outputting column by column.

Parameters

IO Type

Supported types are: complex, float, int, short, and byte

Vector Length

The vector length for the input stream.

Rows

The number of rows for the interleaver.

Columns

The number of columns for the interleaver.

Deinterleave

A boolean variable indicating if the block should behave as an interleaver (deinterleave=False) or deinterleaver (deinterleave=true).

Example Flowgraph

Below is a basic interleave/deinterleave example with the matrix interleaver block:

On the interleaver side, the settings are set as follows:

On the deinterleave side, the settings are the same except the deinterleave variable is set to true:

The output is then captured with a QT GUI Time Sink block. The first signal is the input from the vector source (numbers 0 to 11). The second trace is the interleaved signal following the example in the description section. The third trace is the deinterleaved signal which matches the vector source output.
