Title: System for error control by subdividing coded information units into subsets reordering and interlacing the subsets, to produce a set of interleaved coded information units

Abstract: The invention provides a method of interleaving information units in order to provide improved error control. A communication device codes the information units, subdivides the coded information units into multiple subsets, reorders each of the multiple subsets, and interlaces the multiple reordered subsets to produce a set of interleaved coded information units. By reordering and interlacing the subsets, the impact of burst errors is diminished and the coded information units are formatted to take advantage of the different levels of error protection provided to the various bits underlying a symbol assigned by a symbol mapper.
