Error-Correction Coding and Decoding

This book discusses both the theory and practical applications of self-correcting data, commonly known as error-correcting codes. The applications included demonstrate the importance of these codes in a wide range of everyday technologies, from smartphones to secure communications and transactions. Written in a readily understandable style, the book presents the authors’ twenty-five years of research organized into five parts:

Part I is concerned with the theoretical performance attainable by using error correcting codes to achieve communications efficiency in digital communications systems.

Part II explores the construction of error-correcting codes and explains the different families of codes and how they are designed. Techniques are described for producing the very best codes.

Part III addresses the analysis of low-density parity-check (LDPC) codes, primarily to calculate their stopping sets and low-weight codeword spectrum which determines the performance of th

ese codes.

Part IV deals with decoders designed to realize optimum performance.

Part V describes applications which include combined error correction and detection, public key cryptography using Goppa codes, correcting errors in passwords and watermarking.

This book is a valuable resource for anyone interested in error-correcting codes and their applications, ranging from non-experts to professionals at the forefront of research in their field.

Professor Martin Tomlinson is best known for inventing the Tomlinson-Harashima pre-coding technique. He received his PhD on the subject of adaptive equalisation for data transmission from Loughborough University in 1970. He later worked at Plessey Telecommunications Research Ltd. in the field of digital and satellite transmissions and then at the Satellite Communications Division of the Royal Signals and Radar Establishment (RSRE) (now Qinetiq). He was also the project manager for the communications aspects of the NATO IV satellite before joining the University of Plymouth as the head of the Communication Engineering Department in 1982. Professor Tomlinson has published 186 papers, holds 33 patents and is a well known member of several professional institutes and societies. He is Emeritus Professor of Communications at the University of Plymouth and is also Chief Scientific Officer of Post-Quantum, a company specializing in secure communications and cryptographic products.
