Block Interleaving

You can open the Block sublibrary by double-clicking on the Block icon in the main Interleaving library, or by typing commblkintrlv2 at the MATLAB prompt.

Tip    In this document, you can jump to a block's reference page by clicking on its icon below.

The table below lists and describes the blocks in the Block sublibrary of the Interleaving library. For information about a specific block, see the reference pages that follow; for a discussion of this library's capabilities, see Block Interleavers.
