Abstract
An interleaver has an input multiplexer that receives a data sequence at an interleaver input and that separates the data sequence into multiple data sub-blocks. The interleaver has a linear feedback shift register that generates an input address sequence. The interleaver has adder circuits that generate output address sequences associated with each data sub-block. The interleaver has memory that stores the data sub-blocks at addresses controlled by the input address sequence. The memory reproduces each data sub-block in an interleaved sequence controlled by the associated output address sequence. The interleaver has an output multiplexer that assembles the interleaved sequences to provide an interleaver output.
