Introduction to Digital Communication Systems

Covering topics in digital communication systems, this book offers descriptions of developments such as turbo-codes and Low Density Parity Check codes. It shows basic ideas of digital communications and their limits of performance. It also presents developments such as coding, modulations and multiple access methods.

This text book covers most of the modern topics in digital communication systems. It brings necessary theoretical knowledge in the developing field. Classical coding theory (block and convolutional codes, Galois fields, hard- and soft-decision decoding) is supplemented by descriptions of newer developments such as turbo-codes and Low Density Parity Check codes. It is a Digital Communications textbook that truly links topics to practical applications. It takes an information-theoretic approach, structured from upper to lower layers, to show basic ideas of digital communications and their limits of performance. It presents new developments such as coding, modulations and multiple access methods. It concludes each chapter with a set of problems for students. A solutions manual is available on the companion website along with PowerPoint slides.
