The introduction of turbo codes in 1993 was a major milestone in coding theory that had spurred a renaissance in iterative decoding, leading to breakthroughs in performance over maximum likelihood decoding. Since then, the works of Gallager in 1963 on low-density parity-check (L…

Battail [1989] shows that an appropriate criterion for the design of long block codes is the closeness of the normalized weight distribution to a Gaussian distribution. A subsequent work shows that iterated product of single parity check codes satisfy this criterion [1994]. Moti…
