Описание: Following a detailed introduction, Chaos Applications in Telecommunications demonstrates how chaotic signals are generated and transmitted. It then details the design of chaotic transmitters and receivers, and describes chaos-based modulation and demodulation techniques. The text examines how a chaos-based spreading sequence outperforms classical pseudorandom sequences, thus enhances security, in selective and nonselective channels. It also develops channel equalization techniques designed for chaotic communications systems by applying knowledge of systems dynamics, linear time-invariant representations of chaotic systems, and symbolic dynamics representations of chaotic systems. The final chapter explains a specific application for optical communications.
Описание: The aim of this book is to provide a coherent and structured presentation of the theory and applications of statistical signal processing in three sections: Part 1: Basic Digital Signal Processing gives an introduction to the topic, discussing sampling and quantization, Fourier analysis and synthesis, Z-transform, and digital filters. Part 2: Model-based Signal Processing covers probability and information models, Bayesian inference, Wiener filter, adaptive filters, linear prediction and hidden Markov models. Part 3: Applications of Signal Processing in Speech, Music, and Telecommunication explains the topics of speech and music processing, echo cancellation, deconvolution and channel equalization, and mobile communication signal processing.
Описание: This text relies on graphics, the language of scientists and engineers, for the physical interpretation of subtle mathematical concepts. It establishes a solid background in Fourier, Laplace, and z transforms, before extending them in later chapters. The author presents a unique matrix-equation-matrix sequence of operations that dispels the mystique of the fast Fourier transform, explores the application of digital signal processing technology to real-time processing, and introduces his own generalization of the Dirac-delta impulse and distribution theory. He also offers extensive referencing to MATLAB® and Mathematica® for solving the examples.

Описание: Recent advancements in communication systems performance have been only possible because of digital signal processing applied in all areas of communication systems development and implementation. Advanced Signal Processing for Communication Systems consists of 20 contributions from researchers and experts.The first group of chapters deals with the audio and video processing for communications applications, including topics ranging from multimedia content delivery over the Internet, through the speech processing and recognition to recognition of non-speech sounds that can be attributed to the surrounding environment.Significant attention is given to orthogonal frequency division multiplexing (OFDM) in its various forms, e.g. HIPERLAN, IEEE 802, 11 a. Aspects of OFDM technology covered include novel forms of modulation and coding, methods of reducing in-band and out-of-band spurious signal generation, and means of reducing the peak-to-average power ratio of an OFDM waveform. In these contributions, a key objective is to return the inherent implementational simplicity of the OFDM technique while enhancing its performance relative to single carrier systems.Digital signal processing for second and third generation systems is represented in the book as well. The topics cover both theoretical issues like spreading sequence design and implementation issues of 3G user equipment modem, and MMSE receivers for CDMA systems. A useful comparison of complexity of channel estimation, equalization and decoding for GSM receivers is discussed, too.The book also includes sections on applications of error control coding, information theory, and digital signal processing for communication systems like modulation, software-defined radio, and channel estimation.Advanced Signal Processing for Communication Systems is written for researchers working on communication systems and signal processing, as well as telecommunications industry professionals.

The topics cover a broad range of underwater acoustic signal processing applications: underwater wireless communciations, array processing for mapping, detection and localization of objects, biotelemetry, speech processing for divers, acoustic imaging, and use of neural networks for underwater signal processing.
Описание: Cell phones, GPS receivers, and CD players are just some of the products that rely on real-time digital signal processing (DSP). This book bridges theory and application of DSP using a step-by-step transition approach. It builds a practical framework that reinforces basic DSP theory using demonstrations, exercises, and projects, exploring MATLAB and real-time DSP hardware. The authors provide downloadable access to source code, example files, test signals, and executable programs required for presented examples, exercises, and projects. The book also offers solutions and challenges throughout.
Описание: This book constitutes the refereed proceedings of the First International Workshop on Multimedia Interactive Protocols and Systems, MIPS 2003, held in Napoli, Italy in November 2003. MIPS continues the form IDMS/PROMS Workshop series.The 34 revised full papers presented were carefully reviewed and selected from more than 130 submissions. The papers are organized in topical sections on wireless multimedia systems, communication protocols for multimedia, scheduling, caching, quality of service architectures, novel communication services, middleware, infrastructure, IP telephony, multimedia applications, and encoding.
Описание: Beside detailed looks at technological issues, from the system protocol to implementation technologies, this book discusses the administrative and industrial aspects of third-generation mobile communications. The international expert authors emphasize existing problems and propose solutions.
Описание: The second edition of this popular text covers a wide range of interrelated topics in array processing to provide an accessible introduction to the field. It reviews new developments in the use of sensors in wireless networks and in the use of distributed sensors for localization. It focuses on the common threads that exist in wavefield analysis, rather than on particular applications. Following an introduction to the basic equations governing different wavefields, the text examines current topics of interest, including distributed sensor array, multi-component sensors, space-time processing, azimuth/elevation estimation, wideband adaptive beamformation, and frequency invariant beamformation.
Описание: Visual information is one of the richest and most bandwidth-consuming modes of communication. To meet the requirements of emerging applications, powerful data compression and transmission techniques are required to achieve highly efficient communication, even in the presence of growing communication channels that offer increased bandwidth.Presenting the results of the author’s years of research on visual data compression and transmission, Advances in Visual Data Compression and Communication: Meeting the Requirements of New Applications provides a theoretical and technical basis for advanced research on visual data compression and communication.The book studies the drifting problem in scalable video coding, analyzes the reasons causing the problem, and proposes various solutions to the problem. It explores the author’s Barbell-based lifting coding scheme that has been adopted as common software by MPEG. It also proposes a unified framework for deriving a directional transform from the nondirectional counterpart. The structure of the framework and the statistic distribution of coefficients are similar to those of the nondirectional transforms, which facilitates subsequent entropy coding.Exploring the visual correlation that exists in media, the text extends the current coding framework from different aspects, including advanced image synthesis—from description and reconstruction to organizing correlated images as a pseudo sequence. It explains how to apply compressive sensing to solve the data compression problem during transmission and covers novel research on compressive sensor data gathering, random projection codes, and compressive modulation.For analog and digital transmission technologies, the book develops the pseudo-analog transmission for media and explores cutting-edge research on distributed pseudo-analog transmission, denoising in pseudo-analog transmission, and supporting MIMO. It concludes by considering emerging developments of information theory for future applications.
Описание: Digital Design of Signal Processing Systems offers a practical guide to designing efficient digital systems, covering the complete spectrum of digital design from a DSP (digital signal processing) perspective.
