BER performance of two PEG-ACE codes and the code designed by Ma and Kwak [6] after 100 decoder iterations. Both codes have 
and 
. The PEG-ACE 
dB code performs slightly better than the code designed by Ma and Kwak for both classes. The PEG-ACE 
dB code performs much better than the Ma and Kwak code for low 
, but 
has slightly higher BER at high
