From the Publisher: Mobile satellite services are set to change with the imminent launch of satellite personal communication services (S-PCS), through the use of non-geostationary satellites. This new generation of satellites will be placed in low earth orbit or medium earth orbit, hence, introducing new satellite design concepts. One of the first texts to cover this rapidly evolving field, this text provides the reader with an overview of mobile satellite systems, from their initial introduction (Inmarsat), current satellite-PCS (referring to such systems as Globalstar), through to Satellite-UMTS and an understanding of the following: The design concepts associated with non-geostationary satellite systems (constellation, link budgets, Doppler) The concepts of UMTS (network architecture, aims, in the context of IMT-2000) and the role foreseen for the satellite component (complementary to terrestrial network, network extension, global availability) Inter-working between satellite and terrestrial networks (network architecture, ATM Adaptation Layer) Radio interface technologies (WB-CDMA, TDMA, transmission environment) Regulatory issues Future services and applications Potential satellite markets (prediction techniques, effect of tariffing policies on potential market) With leading edge information, this valuable resource will be indispensable to researchers, engineers, operators and market evaluators in satellite service industries and research institutions, as well as postgraduates and research students in the field. This is one of the first books to cover the latest developments of network technology in mobile satellite services. Provides in-depth analysis of market prediction methodology and evaluates potential satellite-UMTS markets. Discusses ATM technology via satellite. Describes future services and applications.

A comprehensive introduction to CDMA theory and application Code division multiple access (CDMA) communication is rapidly replacing time- and frequency-division methods as the cornerstone of wireless communication and mobile radio. Theory of Code Division Multiple Access Communication provides a lucid introduction and overview of CDMA concepts and methods for both the professional and the advanced student. Emphasizing the role CDMA has played in the development of wireless communication and cellular mobile radio systems, the author leads you through the basic concepts of mobile radio systems and considers the different principles of multiple access-time division, frequency division, and code division. He then analyzes three major CDMA systems-direct sequence (DS) CDMA systems, frequency hopped (FH) CDMA systems, and pulse position hopped (PPH) CDMA systems. Other topics covered include: * Spread spectrum (SS) technology * Forward error control coding * CDMA communication on fading channels * Pseudorandom signals * Information theory in relation to CDMA communication * CDMA cellular networks Complete with useful appendices providing analyses of the moments of CDMA system decision statistics, Theory of Code Division Multiple Access Communication is a ready reference for every engineer seeking an understanding of the history and concepts of this key communications technology.

Your public spirited wish and proposal to forward a History of Launceston was the first occasion of collecting some materials for that purpose. Though the gauntlet you threw down has not yet been taken up, the putting together, in some form, the contributions, for so many of which the Editor is indebted to you, may help to lead to the desirable object suggested and to you, therefore, this slight and crude sketch is dedicated.

A comprehensive guide to optical fiber communications, from the basic principles to the latest developments in OCDMA for Next-Generation Fiber-to-the-Home (FTTH) systems. Part I starts off with the fundamentals of light propagation in optical fibers, including multiple access protocols, and their enabling techniques. Part II is dedicated to the practical perspectives of Next-Generation Fiber-to-the-Home (FTTH) technology. It covers the key building blocks of OCDMA, devices such as optical encoders and decoders, signal impairments due to noise, and data confidentiality, a unique property of OCDMA. This is followed by hybrid system architectures with TDM and WDM and practical aspects such as system cost, energy efficiency and long-reach PONs. Featuring the latest research, with cutting-edge coverage of system design, optical implementations, and experimental demonstrations in test beds, this text is ideal for students, researchers and practitioners in the industry seeking to obtain an up-to-date understanding of optical communication networks.
集体行动：提高接近正义，调和多层利益？
ISBN：9781107536258，出版年：2012，中图分类号：D91
This volume of essays draws together research on different types of collective actions: group actions, representative actions, test case procedures, derivative actions and class actions. The main focus is on how these actions can enhance access to justice and on how to balance the interests of private actors in protecting their rights with the interests of society as a whole. Rather than focusing on collective actions only as a procedural device per se, the contributors to this book also examine how these mechanisms relate to their broader social context. Bringing together a broad range of scholarship from the areas of competition, consumer, environmental, company and securities law, the book includes contributions from Asian, European and North American scholars and therefore expands the scope of the traditional European and/or American debate.
