Accumulate-repeat-accumulate (ARA) code
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.
- Repeat-accumulate (RA) code — ARA codes with no pre-encoding acumulator and no post-acumulator puncturing reduce to RA codes.
