Description For courses in Digital Communications. Exceptionally accessible, this book presents the often “difficult” concepts of digital communications in an easy-to- understand manner— without diluting the mathematical precision. Using a student-friendly approach, it develops the important techniques in the context of a unified structure (in block diagram form)—providing organization and structure to a field that has, and continues, to grow rapidly, and ensuring that students gain an awareness of the “big picture” even while delving into the details (the most up-to-date modulation, coding, and signal processing techniques that have become the basic tools of our modern era). It traces signals and key processing steps from the information source through the transmitter, channel, receiver, and ultimately to the information sink. NEW - Expanded coverage of error-correction coding—Particularly in the areas of Reed-Solomon codes, turbo codes, and trellis-coded modulation. NEW - Chapter on fading channels—And how to mitigate their degrading effects. Methodically organizes the nomenclature of fading channels, the fading phenomena, and their effects, making them easier to grasp.
Prepares students for disciplines such as mobile communications, which require a basic understanding of how such channels suffer the effects of fading, and how to withstand these degrading effects. NEW - Expanded explanations and descriptions of essential digital communication concepts. NEW - Expanded chapter-end problem sets—Adds question sets (and where to find the answers), as well as CD exercises. NEW - Accompanying CD—Contains the educational version of SystemView software by ELANIX®; over 200 additional communications problems (in addition to the ones at the end of each chapter) which can be solved by using the software; and an extensive tutorial on digital signal processing. Allows students to explore the textbook concepts by viewing waveforms, and changing system parameters in the software to see the effects on the overall system.
Sophisticated concepts presented in an easy-to-understand, intuitive way—Uses simple numerical examples, including detailed step-by-step “how-to” instructions. Helps students readily grasp the newest technology, such as turbo codes, trellis-coded modulation, fading channels, Reed- Solomon codes, PGP encryption. Techniques developed in the context of a unified structure—The structure, in block diagram form, appears at the beginning of each chapter; blocks in the diagram are emphasized, when appropriate, to correspond to the subject of that chapter.
Signal transformations—Organized according to nine functional classes: Formatting and source coding; Baseband signaling; Bandpass signaling; Equalization; Channel coding; Multiplexing and multiple access; Spreading; Encryption; and Synchronization. An emphasis on system goals and trade-offs—e.g., between basic system parameters, such as signal-to-noise ratio, probability of error, and bandwidth (spectral) expenditure. Turbo codes—Features unique, thorough coverage of turbo code concepts and “how-to” examples. Gives students insight into the state-of-the-art technique that allows “squeezing out the last drop” of performance improvement that is theoretically possible by using advanced error- correction techniques. Trellis-coded modulation and Reed-Solomon error-correction codes—Goes beyond simple mathematical description to explain all of the sophisticated math—with analogies of what that math is accomplishing. Exposes students to subtle, but important ideas—how they work and how they can be used as a vehicle for achieving different system goals.
Pretty Good Privacy (PGP)—Explains the key features of how PGP works and how it has evolved. Familiarizes students to the security program that has become the “de facto” standard for e-mail and file encryption. An abundance of illustrations (500) and problems and exercises (300). Expanded coverage of error-correction coding—Particularly in the areas of Reed-Solomon codes, turbo codes, and trellis-coded modulation. Chapter on fading channels—And how to mitigate their degrading effects. Methodically organizes the nomenclature of fading channels, the fading phenomena, and their effects, making them easier to grasp. Prepares students for disciplines such as mobile communications, which require a basic understanding of how such channels suffer the effects of fading, and how to withstand these degrading effects.
