Abstract

We define super codes as the serial concatenation of punctured convolutional codes. Puncturing pattern and interleaver design techniques are presented so as to maximise the free distance of the code and thus the performance at very low bit error rates (BER). The performance of super codes is compared to turbo codes. For BERs around 10/sup -5/, turbo codes perform 0.1, 0.4 and 0.6 dB better than super codes for rates 3/4, 1/2 and 1/3, respectively. However, due to the use of serial concatenation, super codes have an interleaver gain of N/sup -2/, compared to only N/sup -1/ for turbo codes and interleaver size N. Thus, super codes are expected to perform significantly better at BERs around 10/sup -10/.
