Practical Signal<br />

Processing<br />

Mark Owen<br />

The principles of signal processing are<br />

fundamental to the operation of many everyday<br />

devices. This book introduces the basic theory of<br />

digital signal processing, with emphasis on realworld<br />

applications. Sampling, quantisation, the<br />

Fourier transform, filters, Bayesian methods and<br />

numerical considerations are covered, then<br />

developed to illustrate how they are used in audio,<br />

image, and video processing and compression,<br />

and in communications. The book concludes with<br />

methods for the efficient implementation of<br />

algorithms in hardware and software. Intuitive<br />

arguments rather than mathematical ones are<br />

used wherever possible, and links between<br />

various signal processing techniques are stressed.<br />

The advantages and disadvantages of different<br />

approaches are presented in the context of realworld<br />

examples, enabling the reader to choose the<br />

best solution to a given problem. With over 200<br />

illustrations and over 130 exercises (including<br />

solutions), this book will appeal to practitioners<br />

working in signal processing, and undergraduate<br />

students of electrical and computer engineering.<br />

Principles of Digital<br />

Communication<br />

Robert Gallager<br />

Massachusetts Institute of<br />

Technology<br />

The renowned communications theorist Robert<br />

Gallager brings his lucid writing style to the study<br />

of the fundamental system aspects of digital<br />

communication for a one-semester course for<br />

graduate students. With the clarity and insight that<br />

has characterized his teaching and earlier<br />

textbooks, he develops a simple framework and<br />

then combines this with careful proofs to help the<br />

reader understand modern systems and simplified<br />

models in an intuitive yet precise way. A strong<br />

narrative and links between theory and practice<br />

reinforce this concise, practical presentation. The<br />

book begins with data compression for arbitrary<br />

sources, Gallager then describes how to modulate<br />

the resulting binary data for transmission over<br />

wires, cables, optical fibers, and wireless<br />

channels. Analysis and intuitive interpretations are<br />

developed for channel noise models, followed by<br />

coverage of the principles of detection, coding,<br />

and decoding. The various concepts covered are<br />

brought together in a description of wireless<br />

communication, using CDMA as a case study.<br />

Contents: Preface; 1. Introduction to digital<br />

communication; 2. Coding for discrete sources;<br />

3. Quantization; 4. Source and channel<br />

waveforms; 5. Vector spaces and signal space;<br />

6. Channels, modulation, and demodulation;<br />

7. Random processes and noise; 8. Detection,<br />

coding and decoding; 9. Wireless digital<br />

This is a concise presentation of the concepts<br />

underlying the design of digital communication<br />

systems, without the detail that can overwhelm<br />

students. Many examples, from the basic to the<br />

cutting-edge, show how the theory is used in the<br />

design of modern systems and the relevance of<br />

this theory will motivate students. The theory is<br />

supported by practical algorithms so that the<br />

student can perform computations and<br />

simulations. Leading edge topics in coding and<br />

wireless communication make this an ideal text for<br />

students taking just one course on the subject.<br />

Fundamentals of Digital Communication has<br />

coverage of turbo and LDPC codes in sufficient<br />

detail and clarity to enable hands-on<br />

implementation and performance evaluation, as<br />

well as ‘just enough’ information theory to enable<br />

computation of performance benchmarks to<br />

compare them against. Other unique features<br />

include space-time communication and geometric<br />

insights into noncoherent communication and<br />

equalization.<br />

their computation; 7. Channel coding; 8. Wireless<br />

System modeling and analysis is a standard<br />

activity in every engineering discipline. This text<br />

offers a broad-based introduction to engineering<br />

systems that incorporates material from<br />

mechanical and electrical engineering, and<br />

hydraulic and thermal systems. The overall theme<br />

that distinguishes the text from others is its unified<br />

treatment of disparate physical systems,<br />

emphasizing similarities in both the modeling and<br />

behavior of such lumped-element systems.<br />

Linear graph theory is presented as a unifying<br />

framework for modeling electrical, mechanical,<br />

hydraulic, and thermal systems as lumped<br />

elements. The analysis of system dynamics that<br />

follows is done in the time domain and organized<br />

by behavioral characteristics rather than by<br />

engineering subdisciplines. Next, the Laplace<br />

transform is introduced as a tool for understanding<br />

frequency response. State space methods are<br />

also presented to provide a third perspective on<br />

system behavior. The final chapter covers the<br />

interaction of subcomponents of an overall<br />

system, particularly feedback systems and<br />

feedback control systems. Every chapter includes<br />

a wide variety of examples, as well as exercise<br />

problems, drawn from real-world mechanical,<br />

electrical, hydraulic, chemical and thermal<br />

systems.<br />

Contents: Preface; 1. Fundamental concepts in<br />

time-invariant systems; 8. State space<br />
