Turbo codes are error-correcting codes with performance close to the Shannon theoretical limit [SHA]. These codes have been invented at ENST Bretagne (now TELECOM Bretagne), France, in the beginning of the 90s [BER]. The encoder is formed by the parallel concatenation of two convolutional codes separated by an interleaver or permuter.

Turbo codes in information theory and coding

I'm self-studying turbo codes for a graduate course in coding theory. I understood how turbo codes works by directly reading Berrou' paper and some of the following works on this topic.

For D-ary code, first add extra zero-probability symbols until |X|–1is a multiple of D–1and then group D symbols at a time. Huffman Code is Optimal Instantaneous Code.
