Methods, system, and apparatus for joint error correction coding of a self-decodable payload and a combined payload

Abstract

In an embodiment, a first codeword is generated by error correction encoding a first individual payload, and a second codeword is generated based on bits that are associated with a second individual payload and are interleaved with bits associated with the first individual payload. Another embodiment involves encoding individual payloads, by low density parity check (LDPC) encoding for example, to generate encoded bits including first encoded bits generated by encoding a first individual payload and second encoded bits generated by encoding a second individual payload with which bits that are associated with the first individual payload are combined. Each of the first codeword and the second codeword includes encoded bits based on the bits that are associated with the first individual payload. The first codeword in these embodiments is decodable independently of the second codeword, and is further decodable jointly with the second codeword.
