In the early nineties, turbo codes and its new iterative decoding technique were
introduced, employing this new coding scheme and its decoding algorithm, it was
possible to achieve performance within a few tenths of a dB the Shannon limit for a
bit error rate of 10-5 [1]. This discovery not only had a major impact on the
telecommunications industry, but it also kicked off major research into the area of
channel maximizing coding schemes using iterative decoding now that they knew it was
possible to achieve.
