Lower bound on BER of finite-length turbo codes based on EXIT characteristics

We present a generalized extrinsic information transfer characteristics of the iterative turbo decoding algorithm. By using this tool, we obtain a lower bound on the bit error rate performance of the finite-length turbo codes showing a gentle waterfall over a wide waterfall region.
