Abstract

Systems and techniques for transmitting an Irregular Systematic with Serially Concatenated Parity (Ir-S-SCP) are described. The techniques include generating an outer code comprising a plurality of bits using systematic bits as input, repeating the plurality of bits of the outer code a pre-determined number of times to generate at least a first set of repeated bits and a second set of repeated bits, serializing the generated sets of repeated bits, wherein each generated set is serialized in parallel with another generated set, interleaving the generated sets of repeated bits, generating an inner code, the inner code generated in part based on the interleaved sets, puncturing the inner code to output parity bits, wherein the puncturing is non-uniform and the puncturing is based at least in part on an incremental redundancy scheme, and transmitting the parity bits, wherein the transmitted parity bits and the systematic bits comprise the Ir-S-SCP code.
