As the feature size decreases in deep sub-micron designs, coupling
capacitance becomes the dominant factor in total capacitance. The
resulting crosstalk noise may be responsible for signal integrity
issues and significant timing variation. Traditionally, static
timing analysis tools have ignored cross coupling effects between
wires altogether. Newer tools simply approximate the coupling
capacitance by a 2X Miller factor in order to compute the worst
case delay. The latter approach not only reduces delay calculation
accuracy, but can also be shown to underestimate the delay in
certain scenarios. -Spatial pruning - reducing aggressors to those in physical
proximity,
"Satellite Network Robust QoS-aware Routing" presents a novel routing strategy for satellite networks. This strategy is useful for the design of multi-layered satellite networks as it can greatly reduce the number of time slots in one system cycle. The traffic prediction and engineering approaches make the system robust so that the traffic spikes can be handled effectively. The multi-QoS optimization routing algorithm can satisfy various potential user requirements. Clear and sufficient illustrations are also presented in the book. As the chapters cover the above topics independently, readers from different research backgrounds in constellation design, multi-QoS routing, and traffic engineering can benefit from the book. Fei Long is a senior engineer at Beijing R&D Center of 54th Research Institute of China Electronics Technology Group Corporation.

In order to adapt to the ever-increasing demands of telecommunication needs, today 's network operators are implementing 100 Gb/s per dense wavelength division multiplexing (DWDM) channel transmission. At those data rates, the performance of fiberoptic communication systems is degraded significantly due to intra- and inter-channel fiber nonlinearities, polarization-mode dispersion (PMD), and chromatic dispersion. In order to deal with those channel impairments, novel advanced techniques in modulation and detection, coding and signal processing are needed. This unique book represents a coherent and comprehensive introduction to the fundamentals of optical communications, signal processing and coding for optical channels. It is the first to integrate the fundamentals of coding theory with the fundamentals of optical communication.

The deployment of high-order modulation formats in optical fiber transmission systems is presently seen as a promising way of increasing spectral efficiency and of making better use of the capacity of currently existing fiber infrastructure. Catering to this interest, this book presents possible ways of generating and detecting optical signals with high-order phase and quadrature amplitude modulation and characterizes their system and transmission properties. Several implementation options for high-order modulation optical transmitters are possible. Their optical and electrical parts are described and their individual signal properties are discussed. Receiver concepts with direct detection, homodyne differential detection and homodyne synchronous detection are illustrated, starting with optical frontends and ending with concrete data recovery. The description of transmitters and receivers provided in the first part of the book not only helps to demonstrate their functioning, but also allows their complexity and practicability to be estimated and compared. To advance understanding of the system and transmission behavior of high-order modulation formats for optical fiber transmission, various system parameters such as noise performances, optimal receiver filter bandwidths, required laser linewidths and the chromatic dispersion and self phase modulation tolerances of a wide range of modulation formats are highlighted in the second part of the book, considering different line codes and many transmitter and receiver configurations. Currently, the determination of attainable transmission distances for multi-span long-haul transmission using high-order modulation formats represents an exciting field of research. Recent results in this area are also covered by this book. This monograph is intended for students and researchers in the field of optical communications, as well as for system designers who want to learn about the properties and complexity of optical systems employing high-order modulation.

This book introduces an efficient resource management approach for future spectrum sharing systems. The book focuses on providing an optimal resource allocation framework based on carrier aggregation to allocate multiple carriers' resources efficiently among mobile users. Furthermore, it provides an optimal traffic dependent pricing mechanism that could be used by network providers to charge mobile users for the allocated resources. The book provides different resource allocation with carrier aggregation solutions, for different spectrum sharing scenarios, and compares them. The provided solutions consider the diverse quality of experience requirement of multiple applications running on the user's equipment since different applications require different application performance. In addition, the book addresses the resource allocation problem for spectrum sharing systems that require user discrimination when allocating the network resources.
A successful cyber-physical system, a complex interweaving of hardware and software with some part of the physical environment, depends on proper identification of the, often pre-existing, physical element. A bespoke "cyber" part of the system may then be designed from scratch. Optimal Mobile Sensing and Actuation Strategies in Cyber-physical Systems focuses on distributed-parameter systems the dynamics of which can be modelled with partial differential equations. These are very challenging to observe, their states and inputs being distributed throughout a spatial domain. Consequently, systematic approaches to the optimization of sensor location have to be devised for parameter estimation. The text begins by reviewing the field of cyber-physical systems and introducing background notions of distributed parameter systems and optimal observation theory. New research problems are then defined within this framework. Two important problems considered are optimal mobile sensor trajectory planning and the accuracy effects and allocation of remote sensors. These are followed up with a solution to the problem of optimal robust estimation. Actuation policies are then introduced into the framework with the purpose of improving estimation and optimizing the trajectories of both sensors and actuators simultaneously. The large number of illustrations within the text will assist the reader to visualize the application of the methods proposed. A group of similar examples are used throughout the book to help the reader assimilate the material more easily. The monograph concentrates on the use of methods for which a cyber-physical-systems infrastructure is required. The methods are computationally heavy and require mobile sensors and actuators with communications abilities. Application examples cover fields from environmental science to national security so that readers are encouraged to link the ideas of cyber-physical systems with their own research.

This dictionary is a collection of technical abbreviations and acronyms used in information and communication technologies and other industrial activities. They are used in industries, institutes, organisations and universities, all too often without mentioning their meaning. Areas covered by this dictionary are Information and Communication Technology (ICT), including hardware and software; Information Networks, including the Internet and the World Wide Web; Automatic Control; and ICT-related Computer-Aided Techniques and Activities. Apart from the technical terms this dictionary also lists abbreviated names of relevant organisations, conferences, symposia and workshops. This reference book is important for all practitioners and users in the areas mentioned above and those who consult or write technical material (manuals, guides, books, articles, marketing and teaching material). These publications often omit the meaning of acronyms and confront the reader with jargon too often difficult to understand. This edition contains over 33,000 items and differs from the previous one by deleting obsolete terms and less relevant acronyms. Ten thousand new items have been added. |
