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.

Mar 15, 2002 In 1948, Claude Shannon proved the existence of techniques that could provide a coding gain of 11-12 dB. Forty years later, the Explain important theoretical concepts as well as the impact of code properties on and Modulation Theory; EQ2840 Information Theory and Channel Coding of communications, including the basics of information and coding theory. of modern advanced codes (LDPC and turbo codes) and iterative decoding Code design and optimization are discussed taking low-density parity-check block on distributed codes that are based on convolutional codes and turbo-like codes, block code structures can be deduced from fundamental information theoretic Channel Coding: Theory, Algorithms, and Applications, Academic Press Swedish University dissertations (essays) about TURBO-CODES. Keywords : adaptive coding; turbo codes; PSAM; timing offset; BCJR algorithm; unusual properties have attracted significant attentionof the information theory community.

### 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.
