This newly revised and expanded edition of an Artech House classic builds on its success as far and away the most comprehensive guide to digital modulation techniques used in communications today. The second edition adds a wealth of up-to-date, critical material, including: Five new chapters devoted to orthogonal frequency division multiplexing (OFDM) covering its basics and practical implementation issues: peak-to-average power ratio (PAPR) reduction, synchronization, fading channel performance, and mitigation methods, as well as the newest developments such as wavelet OFDM schemes; New modulations for optical communications; Enhanced coverage of M-ary amplitude shift keying (ASK); More accurate bit error rate (BER) equations for quaternary phase shift keying (QPSK) and quadrature amplitude modulation (QAM); Enhanced coverage of fading channel mitigation methods such as channel estimate and diversity techniques; Fast-access comparison of all modulation schemes; New appendixes covering trigonometry identities, Fourier transform pairs and properties, and Q-function and error function values.

The focus of this book is broadband telecommunications: both fixed (DSL, fiber) and wireless (1G-4G). It uniquely covers the broadband telecom field from technological, business and policy angles. The reader learns about the necessary technologies to a certain depth in order to be able to evaluate and analyse competing technologies. The student can then apply the results of the technology analysis to business (revenues and costs, market size, etc) to evaluate how successful a technology may be in the market place. Technology and business analyses lead to policy analysis and how government deal with rolling out of broadband networks; content (such as text, audio and video) delivered over them. Furthermore, how government may ensure a competitive and fair environment is maintained for service provision. The book is unique in its approach as it prepares the student to evaluate products from three different viewpoints of technology-business and policy. The book provides a unified vision for broadband communications, offering the required background as well a description of existing broadband systems, finishing with a business scenario. The book breaks new ground by discussing telecommunication technologies in a business and policy context.

A concise introduction to the core concepts in digital communication, providing clarity and depth through examples, problems and MATLAB exercises. Its simple structure maps a logical route to understand the most basic principles in digital communication, and also leads students through more in-depth treatment with examples and step-by step instructions.

There have been considerable developments in information and communication technology. This has led to an increase in the number of applications available, as well as an increase in their variability. As such, it has become important to understand and master problems related to establishing radio links, the layout and flow of source data, the power available from antennas, the selectivity and sensitivity of receivers, etc. This book discusses digital modulations, their extensions and environment, as well as a few basic mathematical tools. An understanding of degree level mathematics or its equivalent is a prerequisite to reading this book. Digital Communication Techniques is aimed at licensed professionals, engineers, Masters students and researchers whose field is in related areas such as hardware, phase-locked loops, voltage-controlled oscillators or phase noise.
