Abstract
The "error floor" observed in several simulations with the turbo
codes is verified by calculation of an upper bound to the bit
error rate for the ensemble of all interleavers. Also an easy way
to calculate the weight enumerator used in this bound is
presented. An extended coding scheme is proposed including an
outer BCH code correcting a few bit errors.
