The book addresses the study and design of efficient and flexible physical layers for broadband mobile and fixed satellite links. The chapters focus on long-term developments addressing advanced physical layer techniques for braodband communications, fixed and mobile terminals, and 4G evolutions with possible convergence betwee different technologies. The book provides a unified view of services and applications, fundamental theories, channel coding, modulation, synchronization and parameter estimation, distortions and countermeasures, diversity techniques, multiplexing and multiple access schemes, and software radio.

Designed for senior electrical engineering students, this textbook explores the theoretical concepts of digital signal processing and communication systems by presenting laboratory experiments using real-time DSP hardware. Originally designed for the Texas Instruments TMS320C6701 Evaluation Module or TMS320C6711 DSK, this new editionupdates the experiments based on the TMS320C6713 (but can easily be adapted to other DSP boards). Each chapter begins with a presentation of the required theory and concludes with instructions for performing experiments to implement the theory. In the process of performing the experiments, students gain experience in working with software tools and equipment commonly used in industry. The primary focus of this book is on communication systems. Algorithms that are particularly suited to DSP implementations are presented. Chapters 1 and 2 introduce the software and hardware tools. Chapter 3 presents FIR and IIR digital filters and Chapter 4 investigates the FFT. Chapters 4 through 8 discuss modulators and demodulators for classical analog modulation methods such as amplitude modulation (AM), double-sideband suppressed-carrier amplitude modulation (DSBSC-AM), single sideband modulation (SSB), and frequency modulation (FM). Chapters 9 through 16 explore digital communication methods leading to the implementation of a complete telephone-line modem. These chapters include shift register pseudo-random binary sequence generators, the RS-232 protocol, pulse amplitude modulation (PAM), quadrature amplitude modulation (QAM) transmitters and receivers, and echo cancellation. Methods for adaptive equalization, carrier recovery, and symbol clock tracking are presented. Chapter 17 gives suggestions for additional experiments.

This book brings together the latest research achievements from various areas of signal processing and related disciplines in order to consolidate the existing and proposed new directions in DSP based knowledge extraction and information fusion. Within the book contributions presenting both novel algorithms and existing applications, especially those (but not restricted to) on-line processing of real world data are included. The areas of Knowledge Extraction and information Fusion are naturally linked and aim at detecting and estimating the signal of interest and its parameters, and further at combining measurements from multiple sensors (and associated databases if appropriate) to achieve improved accuracies and more specific inferences which cannot be achieved by using only a single signal modality. The subject therefore is of major interest for modern biomedical, environmental, and industrial applications to provide a state of the art and propose new techniques in order to combine heterogeneous information sources.

This book contains a thorough discussion of the classical topics in information theory together with the first comprehensive treatment of network coding, a subject first emerged under information theory in the mid 1990's that has now diffused into coding theory, computer networks, wireless communications, complexity theory, cryptography, graph theory, etc. With a large number of examples, illustrations, and original problems, this book is excellent as a textbook or reference book for a senior or graduate level course on the subject, as well as a reference for researchers in related fields.

Cellular Communications is about Service, technology and Economy. Public awareness and safety is considered the fourth dimension in the equation, that rolls back to impact all of the other three. Mobile communications has become an indispensable element of modem lifestyle. The 3G cellular systems focus on high data-rate multimedia services and a host of respective applications, mostly leisure-time oriented. At the other extreme, mobile communications is a most effective driving force in boosting the economy of developing communities. These two processes may share technology momentum and the economy of scale, but their substantial differences have to be recognized, at the time when the momentum of cellular deployment moves in that direction. The introduction of mobile wireless services to developing communities is challenged by the cost of infrastructure, operations and user terminals of the advanced networks, and the mixture of older generation systems to coexist with the new deployments. Affordability considerations and priority of services inspire innovative architectural and optimization solutions to the infrastructure, choice of applications and user terminals.
