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.

In this paper we discuss AWGN coding theorems for ensembles of coding systems which are built from fixed convolutional codes interconnected with random interleavers. We call these systems “turbo-like” codes and they include as special cases both the classical turbo codes [1,2,3] and the serial concatentation of interleaved convolutional codes [4].

Codes are used for data compression, cryptography, error-correction, and networking. Codes are studied by various scientific disciplines—such as information theory, electrical engineering, mathematics, linguistics, and IEEE TRANSACTIONS ON INFORMATION THEORY.

IEEE TRANSACTIONS ON INFORMATION THEORY, VOL. 48, NO. 6, JUNE 2002 1451 Coding Theorems for Turbo Code Ensembles Hui Jin and Robert J. 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.
