(PCCC), called turbo codes, has increased the interest in the coding area since these codes give most of the gain promised by the channel-coding theorem. 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
in the original turbo code construction. Nevertheless, the nature of the relatively simple ad hoc turbo-decoding algorithm has re- mained something of a mystery.
The inventors Claude Berrou, Alain Glavieux, and Punya Thitimajshima, are all from IMT Atlantique (formerly Télécom Bretagne, formerly ENST Bretagne), France. 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.

The codeword in a turbo code consists of the input bits - i.e. the code is systematic - followed by the parity check bits from the first encoder and then the parity bits from the second encoder, as
More than ten years after their introduction, turbo Codes are now a mature technology that has been rapidly adopted for application in many commercial transmissions systems. 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.

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 purpose of this Special Issue is to shed light on these novel developments.

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.
11. 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 invention of turbo codes, first published in 1993, is a landmark event in information theory and telecommunication engineering.
