We consider a serial cascade of an array of repetition codes, an interleaver, and a TC. Such a coding scheme was introduced in [l] as irregular turbo code (ITC). A lower bound on the protection level [2, 31 of the ITC is pre-Theorem 1 Given a rate R = Rob/ ( c + 1) ITC with L rate Ro31 outer repetition codes and a rate
