Abstract
Methods, apparatuses, and systems are presented for performing data encoding involving encoding data bits according to an outer convolutional code to produce outer encoded bits, processing the outer encoded bits using an interleaver and a single parity check (SPC) module to produce intermediate bits, encoding the intermediate bits according to an inner convolutional code to produce inner encoded bits, processing the inner encoded bits using a puncture module to produce punctured bits, and combining the data bits and the punctured bits to produce encoded outputs. Methods, apparatuses, and systems are also presented for performing data decoding based on soft channel metrics derived from a channel using various iterative techniques.
