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. INFORMATION THEORY & CODING Dr. Rui Wang Department of Electrical and Electronic Engineering Southern Univ. of Science and Technology (SUSTech) Email: wang.r@sustech.edu.cn September 8, 2020 Dr. Rui Wang (EEE) INFORMATION THEORY & CODING September 8, 20201/62 In recent years, information theorists have tackled a multitude of new interesting problems for which novel channel coding schemes were devised. The purpose of this Special Issue is to shed light on these novel developments. Researchers are highly encouraged to submit their recent findings in the field of information and coding theory.

Turbo codes in information theory and coding

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 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].

Coding Theory provides algorithms and architectures used for implementing coding and decoding strategies as well as coding schemes used in practice especially in communication systems.

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. 2021-04-02 · 2. Error-detecting codes Chung-Hsuan Wang 3.

Given that, Turbo Codes: Promises and Challenges (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.

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.
