Introduction to Digital Communications is a comprehensive third- and fourth-year undergraduate-level and first-year graduate level textbook focusing exclusively on all critical elements of digital communications. Written by Ali Grami, lead researcher and principal designer of the world's first broadband access satellite system, the book demonstrates the basic principles in the analysis and design of digital communication systems in a coherent fashion, and introduces the underlying design objectives and constraints. Descriptive applications, intuitive explanations, practical examples, and technological advances in the field are hallmark features of this book, which begins by laying a solid foundation of signals and systems. The book discusses analog-to-digital & digital-to-analog conversions, since the modalities perceived by humans, such as speech, music, image and video, are all in analog and yet the transmission is in digital. The text also fully describes digital baseband transmission and modulation techniques, source coding (e.g., digital compression) to reduce transmission rate and storage requirements, and channel coding (e.g., digital error control) to improve performance, highlighting major aspects of multi-user communications and providing a complete chapter on digital communication applications. * The first and only undergraduate textbook to provide comprehensive and detailed coverage of all major topics in digital communications, including source and channel coding techniques* Provides clear descriptions and intuitive explanations of all theoretical and complex concepts, with an emphasis on not only what and how, but also on why* Includes significant discussions on design objectives and valuable insight into design constraints, along with their imperative trade-offs* Contains numerous descriptive applications and practical examples throughoutReseña del editor:
Introduction to Digital Communications explores the basic principles in the analysis and design of digital communication systems, including design objectives, constraints and trade-offs. After portraying the big picture and laying the background material, this book lucidly progresses to a comprehensive and detailed discussion of all critical elements and key functions in digital communications. * The first undergraduate-level textbook exclusively on digital communications, with a complete coverage of source and channel coding, modulation, and synchronization.* Discusses major aspects of communication networks and multiuser communications* Provides insightful descriptions and intuitive explanations of all complex concepts* Focuses on practical applications and illustrative examples.* A companion Web site includes solutions to end-of-chapter problems and computer exercises, lecture slides, and figures and tables from the text
