Abstract
The author discusses the group property of turbo-codes when considered as a periodic linear system. It is shown that the interleaving procedure provides a homomorphism between different encoded sequences and thereby breaks the low weight sequences by a factor of, at most, 1/2r, where r is the constraint length of the code
