This chapter is a general introduction to the original turbo codes discovered in the early 1990s and known as convolutional turbo codes or parallel concatenated convolutional codes. It presents the main concepts of coding theory introduced with the invention of turbo codes, put in a historical perspective.

Because turbo codes did not actually results from applying a pre existing theory, most of their outstanding features remain to be explained. The objective of this paper is to Coding theory is the study of the properties of codes and their respective fitness for specific applications. Codes are used for data compression, cryptography, error detection and correction, data transmission and data storage. Codes are studied by various scientific disciplines—such as information theory, electrical engineering, mathematics, linguistics, and computer science—for the purpose of designing efficient and reliable data transmission methods.

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. Instead of concatenating in serial, codes can also be concatenated in parallel. The original turbo code is a parallel concatenation of two recursive systematic convolutional(RSC) codes. "systematic: one of the outputs is the input.

The inventors Claude Berrou, Alain Glavieux, and Punya Thitimajshima, are all from IMT Atlantique (formerly Télécom Bretagne, formerly ENST Bretagne), France. Turbo Codes! Backgound " Turbo codes were proposed by Berrou and Glavieux in the 1993 International Conference in Communications. " Performance within 0.5 dB of the channel capacity limit for BPSK was demonstrated.!

The authors begin with many practical applications in coding, including the repetition code, the Hamming code and the Huffman code. They then explain the corresponding information theory, from entropy and mutual information to channel capacity and the information transmission theorem.

Instead of concatenating in serial, codes can also be concatenated in parallel. The original turbo code is a parallel concatenation of two recursive systematic convolutional(RSC) codes.

McEliece, Fellow, IEEE Invited Paper Abstract— This paper is devoted to a Shannon-theoretic study of turbo codes. We prove that ensembles of parallel and serial turbo codes are “good” in the following sense. version of turbo codes employing two eight-state convolutional codes as constituent codes, an interleaver of 32 x 32 bits and an iterative decoder performing two and a half iterations with a complexity of the order of nine times the ML Viterbi decoding of each constituent code is presently available on a Turbo codes Turbo Conv.
