Abstract

The present invention relates to methods, apparatuses, and systems For performing data encoding involving encoding data bits, according to an outer convolutional (804) code to produce outer encoded bits processing the outer encoded bits using an interleaver (808) and a logical unit (812) to produce intermediate bits, wherein the logical unit (812) receives a first number of input bits and produces a second number of corresponding output bits, the second number being less than the first number, and wherein the logical unit (812) takes each of the first number of input bits into account in producing the second number of output bits, encoding the intermediate bits according to an inner convolutional code (806) to produce inner encoded bits, wherein the inner con\ olutional code is characterized by at least two states, and combining the data bits and the inner encoded bits to produce encoded outputs.
