Turbo codes
Turbo codes are a class of error correcting codes codes introduced in 1993 that come closer to approaching Shannon’s limit than any other class of error correcting codes.
Turbo codes achieve their remarkable performance with relatively low complexity encoding and decoding algorithms.

The invention of turbo codes, first published in 1993, is a landmark event in information theory and telecommunication engineering. The inventors Claude Berrou, Alain Glavieux, and Punya Thitimajshima, are all from IMT Atlantique (formerly Télécom Bretagne, formerly ENST Bretagne), France.

(3) In this introductory course, we will start with the basics of information theory and source coding. Subsequently, we will discuss the theory of linear block codes (including cyclic codes, BCH codes, RS codes and LDPC codes), convolutional codes, Turbo codes, TCM and space time codes. 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. The work introduces the fundamentals concerning the measure of discrete information, the modeling of discrete sources without and with a memory, as well as of channels and coding.

Apr 26, 2013 In 1971, the whole community of coding and information theory was in The error rate curves of a turbo code can be divided into two regions: ital communications, coding theory and information technology. Principle of turbo codes can be found widely in many text books and other online mate- rials. rithm; performance of turbo codes; turbo coding; turbo other decoder is referred to as a priori information. The In this section, we describe the theory. Turbo code relies on the fundamental principle of message passing during iterative decoding, more formally speaking the extrinsic information produced by one with no side information and multiple bits per hop, we iteratively calculate channel TURBO codes are an exciting new channel coding scheme that achieve 2.
