Achieving the Shannon limit by turbo coding 8. Other aspects of coding theory Francis Lu. 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. INFORMATION THEORY & CODING Dr. Rui Wang Department of Electrical and Electronic Engineering Southern Univ.
Researchers are highly encouraged to submit their recent findings in the field of information and coding theory. Turbo codes are used in 3G/4G mobile communications (e.g. in UMTS and LTE) and in (deep space) satellite communications as well as other applications where designers seek to achieve reliable information transfer over bandwidth- or latency-constrained communication links in the presence of data-corrupting noise. These error-correcting codes were invented by Robert Gallager in the early 1960’s, and re-invented and shown to have very good performance by David MacKay and myself in the mid-1990’s. The decoding algorithm for LDPC codes is related to that used for Turbo codes, and to probabilistic inference methods used in other fields. The turbo-code encoder is built using a parallel concatenation of two recursive systematic convolutional codes, and the associated decoder, using a feedback decoding rule, is implemented as P pipelined identical elementary decoders. Types of Coding •Source Coding - Code data to more efficiently represent the information – Reduces “size” of data – Analog - Encode analog source data into a binary for-mat – Digital - Reduce the “size” of digital source data •Channel Coding - Code data for transmition over a noisy communication channel – Increases “size The cost of using channel coding to protect the information is a reduction in data rate or an Theory [Wic95].

Turbo codes are the error-coding schemes applied nowadays in wireless networks. In naval applications, the information is mostly sent through wireless networks and the data is more prone to noise. 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.
