Error Control Coding

Error-controlled coding techniques are used to detect and/or correct errors that occur in the message transmission in a digital communications system. Wireless personal channels used by mobile communications systems and storage systems for digital multimedia data all require the implementation of error control coding methods. Demonstrating the role of coding in communication and data storage system design, this text illustrates the correct use of codes and the selection of the right code parameters. Relevant decoding techniques and their implementation are discussed in detail. Providing communication systems engineers and students with guidance in the application of error-control coding, this book emphasizes the fundamental concepts of coding theory while minimising the use of mathematical tools.
* Reader-friendly approach ti coding in communication systems providing examples of encoding and decoding, information theory and criteria for code selection
* Thorogh descriptions of relevant application, including telephony on satellite links, GSM, UMTS and multimedia standards, CD, DVD and MPEG
* Provides coverage of the fundamentals of coding and the applications of codes to the design of real error control systems
* End of chapter problems to test and develop understandingFehlerkontrollsysteme werden zur Entdeckung und/oder Korrektur von Fehlern verwendet, die bei der Datenübertragung in digitalen Kommunikationssystemen auftreten. Dieses Buch erläutert die Rolle der Fehlerkontrollcodierung in Kommunikations- und Datenspeichersystemen und zeigt, wie man den richtigen Code mit den geeigneten Parametern auswählt. Relevante Decodierungstechniken und ihre Implementierung werden beschrieben. Obwohl alle Grundkonzepte der Codierungstheorie zur Sprache kommen, bleibt die Verwendung mathematischer Formalismen auf ein Mindestmaß beschränkt. Gründlich besprochen werden Anwendungen für Satellitentelefone, GSM, UMTS und Multimediastandards, CD, DVD und MPEG. Aufgaben am Ende der Kapitel helfen bei der Selbstkontrolle.

Peter Sweeney is the author of Error Control Coding: From Theory to Practice, published by Wiley. Error Control Coding: From Theory to Practice provides a concise introduction to basic coding techniques and their application. The fundamental concepts of coding theory are explained using simple examples with minimum use of complex mathematical tools. The selection of appropriate codes and the design of decoders are discussed.

Bridging the gap between digital communications and information theory, this accessible approach will appeal to students and practising engineers alike.

The clear presentation and practical emphasis make this book an excellent tool for both communications and electronic engineering students. Practitioners new to the field will find this text an essential guide to coding.
