Accumulate-repeat-accumulate (ARA) code[1]
Description
A generalization of the RA code in which the outer repetition-code encoding step is augmented with an acumulator acting on a fraction of the incoming bits. In addition, the code may be punctured after the final acumulating step.
Parents
- Irregular LDPC code
- Protograph LDPC code — ARA codes can be formulated as protograph LDPC codes [2].
Child
- Repeat-accumulate (RA) code — ARA codes with no pre-encoding acumulator and no post-acumulator puncturing reduce to RA codes.
