Cambridge University Press The Mathematics of Signal Processing Cambridge Texts in Applied Mathematics Series Number 48
Book SynopsisArising from courses taught by the authors, this largely self-contained treatment is ideal for mathematicians who are interested in applications or for students from applied fields who want to understand the mathematics behind their subject. Early chapters cover Fourier analysis, functional analysis, probability and linear algebra, all of which have been chosen to prepare the reader for the applications to come. The book includes rigorous proofs of core results in compressive sensing and wavelet convergence. Fundamental is the treatment of the linear system y=Îx in both finite and infinite dimensions. There are three possibilities: the system is determined, overdetermined or underdetermined, each with different aspects. The authors assume only basic familiarity with advanced calculus, linear algebra and matrix theory and modest familiarity with signal processing, so the book is accessible to students from the advanced undergraduate level. Many exercises are also included.Trade Review'Damelin and Miller provide a very detailed and thorough treatment of all the important mathematics related to signal processing. This includes the required background information found in elementary mathematics courses, so their book is really self-contained. The style of writing is suitable not only for mathematicians, but also for practitioners from other areas. Indeed, Damelin and Miller managed to write their text in a form that is accessible to nonspecialists, without giving up mathematical rigor.' Kai Diethelm, Computing Reviews'In the last 20 years or so, many books on wavelets have been published; most of them deal with wavelets from either the engineering or the mathematics perspective, but few try to connect the two viewpoints. The book under review falls under the last category … Overall, the book is a good addition to the literature on engineering mathematics.' Ahmed I. Zayed, Mathematical ReviewsTable of Contents1.

Cambridge University Press Foundations of Signal Processing
Book SynopsisThis comprehensive, accessible textbook covers the basics of signal processing, building up from fundamental principles to practical applications. It uses engineering notation to make mathematical concepts easy to follow, includes numerous homework problems and is accompanied by an extensive Mathematica® companion and instructor solutions manual.Trade Review'This is a major book about a serious subject - the combination of engineering and mathematics that goes into modern signal processing: discrete time, continuous time, sampling, filtering, and compression. The theory is beautiful and the applications are so important and widespread.' Gil Strang, Massachusetts Institute of Technology'A refreshing new approach to teaching the fundamentals of signal processing. Starting from basic concepts in algebra and geometry, [the authors] bring the reader to deep understandings of modern signal processing. Truly a gem!' Rico Malvar, Microsoft Research'A wonderful book that connects together all the elements of modern signal processing … it's all here and seamlessly integrated, along with a summary of history and developments in the field. A real tour-de-force, and a must-have on every signal processor's shelf!' Robert D. Nowak, University of Wisconsin, Madison'Finally a wonderful and accessible book for teaching modern signal processing to undergraduate students.' Stéphane Mallat, École Normale Supérieure'Most introductory signal processing textbooks focus on classical transforms, and study how these can be used. Instead, Foundations of Signal Processing encourages readers to think of signals first. It develops a 'signal-centric' view, one that focuses on signals, their representation and approximation, through the introduction of signal spaces. Unlike most entry-level signal processing texts, this general view, which can be applied to many different signal classes, is introduced right at the beginning. From this, starting from basic concepts, and placing an emphasis on intuition, this book develops mathematical tools that give the readers gets a fresh perspective on classical results, while providing them with the tools to understand many state of the art signal representation techniques.' Antonio Ortega, University of Southern California'Foundations of Signal Processing … is a pleasure to read. Drawing on the authors' rich experience of research and teaching of signal processing and signal representations, it provides an intellectually cohesive and modern view of the subject from the geometric point of view of vector spaces. Emphasizing Hilbert spaces, where fine technicalities can be relegated to backstage, this textbook strikes an excellent balance between intuition and mathematical rigor, that will appeal to both undergraduate and graduate engineering students. The last two chapters, on sampling and interpolation, and on localization and uncertainty, take full advantage of the machinery developed in the previous chapters to present these two very important topics of modern signal processing, that previously were only found in specialized monographs. The explanations of advanced topics are exceptionally lucid, exposing the reader to the ideas and thought processes behind the results and their derivation. Students will learn … why things work, at a deep level, which will equip them for independent further reading and research. I look forward to using this text in my own teaching.'

Cambridge University Press Connecting the NineteenthCentury World The Telegraph And Globalization
Book SynopsisBy the end of the nineteenth century the global telegraph network had connected all continents and brought distant people into direct communication 'at the speed of thought' for the first time. Roland Wenzlhuemer here examines the links between the development of the telegraph and the paths of globalization, and the ways in which global spaces were transformed by this technological advance. His groundbreaking approach combines cultural studies with social science methodology, including evidence based on historical GIS mapping, to shed new light on both the structural conditions of the global telegraph network and the historical agency of its users. The book reveals what it meant for people to be telegraphically connected or unconnected, how people engaged with the technology, how the use of telegraphy affected communication itself and, ultimately, whether faster communication alone can explain the central role that telegraphy occupied in nineteenth-century globalization.Trade Review'Wenzlhuemer's Connecting the Nineteenth-Century World is an important and useful book for historians of technology and capitalism. I wish it had been available when I wrote my own on the American telegraph industry.'

Cambridge University Press Samuel F B Morse His Letters And Journals Volume
Book SynopsisThe American inventor Samuel Morse (1791â1872) spent decades fighting to be recognised for his key role in devising the electromagnetic telegraph. While he will always be remembered in the history of telecommunications, and for co-developing the code which bears his name, Morse started out as a painter and also involved himself in matters of politics over the course of his career. Published in 1914, this two-volume collection of personal papers was edited by his son, who provides helpful commentary throughout, illuminating the struggles and successes of a remarkable life. Volume 1 includes observations made in Europe while Morse studied painting. During the Napoleonic wars, he writes letters home describing the rising level of crime and social unrest in London, mentioning that he sleeps with a pistol. He is in London when Spencer Perceval is assassinated and later writes of meeting Turner, 'the best landscape painter living'.Table of ContentsPreface; 1. April 27, 1791–September 8, 1810; 2.

John Wiley & Sons Inc Host Identity Protocol HIP
Book SynopsisWithin the set of many identifier-locator separation designs for the Internet, HIP has progressed further than anything else we have so far. It is time to see what HIP can do in larger scale in the real world. In order to make that happen, the world needs a HIP book, and now we have it. - Jari Arkko, Internet Area Director, IETF One of the challenges facing the current Internet architecture is the incorporation of mobile and multi-homed terminals (hosts), and an overall lack of protection against Denial-of-Service attacks and identity spoofing. The Host Identity Protocol (HIP) is being developed by the Internet Engineering Task Force (IETF) as an integrated solution to these problems. The book presents a well-structured, readable and compact overview of the core protocol with relevant extensions to the Internet architecture and infrastructure. The covered topics include the Bound End-to-End Tunnel Mode for IPsec, Overlay Routable Cryptographic Hash Identifiers, extensTrade Review"I recommend this book to all software writers and engineers who are working in the context of mobile IP, IPv6, and the future internet.
