Описание: Increase the efficient use of time-varying available spectrum with this book, the first to describe RF hardware design for white space applications, including both analog and digital approaches. Including real-world examples, global spectrum regulations and policies, and cross analog and digital design guidelines to help cut design time and cost.
Presents the technological advancements that enable high spectral-efficiency and high-capacity fiber-optic communication systems and networks
This book examines key technology advances in high spectral-efficiency fiber-optic communication systems and networks, enabled by the use of coherent detection and digital signal processing (DSP). The first of this book's 16 chapters is a detailed introduction. Chapter 2 reviews the modulation formats, while Chapter 3 focuses on detection and error correction technologies for coherent optical communication systems. Chapters 4 and 5 are devoted to Nyquist-WDM and orthogonal frequency-division multiplexing (OFDM). In chapter 6, polarization and nonlinear impairments in coherent optical communication systems are discussed. The fiber nonlinear effects in a non-dispersion-managed system are covered in chapter 7. Chapter 8 describes linear impairment equalization and Chapter 9 discusses various nonlinear mitigation techniques. Signal synchronization is covered in Chapters 10 and 11. Chapter 12 describes the main constraints put on the DSP algorithms by the hardware structure. Chapter 13 addresses the fundamental concepts and recent progress of photonic integration. Optical performance monitoring and elastic optical network technology are the subjects of Chapters 14 and 15. Finally, Chapter 16 discusses spatial-division multiplexing and MIMO processing technology, a potential solution to solve the capacity limit of single-mode fibers.
- Contains basic theories and up-to-date technology advancements in each chapter
- Describes how capacity-approaching coding schemes based on low-density parity check (LDPC) and spatially coupled LDPC codes can be constructed by combining iterative demodulation and decoding
- Demonstrates that fiber nonlinearities can be accurately described by some analytical models, such as GN-EGN model
- Presents impairment equalization and mitigation techniques
Enabling Technologies for High Spectral-efficiency Coherent Optical Communication Networks is a reference for researchers, engineers, and graduate students.

Описание: Presenting a multidisciplinary approach on the demand side issues of new information technologies in the home, this text examines how consumers adopt and use Information Technology (IT), the strategies IT marketers use to reach consumers, and the public policies that help and protect consumers.
Описание: This book is the first systematic exposition on the emerging domain of wireless power transfer in ad hoc communication networks. It selectively spans a coherent, large spectrum of fundamental aspects of wireless power transfer, such as mobility management in the network, combined wireless power and information transfer, energy flow among network devices, joint activities with wireless power transfer (routing, data gathering and solar energy harvesting), and safety provisioning through electromagnetic radiation control, as well as fundamental and novel circuits and technologies enabling the wide application of wireless powering. Comprising a total of 27 chapters, contributed by leading experts, the content is organized into six thematic sections: technologies, communication, mobility, energy flow, joint operations, and electromagnetic radiation awareness. It will be valuable for researchers, engineers, educators, and students, and it may also be used as a supplement to academic courses on algorithmic applications, wireless protocols, distributed computing, and networking.
Описание: The Role of Information and Communication Technologies in Postconfl ict Reconstruction studies explores the transformative role that Information and Communication Technologies (ICTs) can have in postconfl ict nations during the process of reconstruction. It examines how policymakers, the donor community, and the private sector have prioritized and sequenced ICT initiatives in the aftermath of confl ict. Case studies look at countries at different stages of post-confl ict reconstruction in Afghanistan, Liberia, Rwanda and Timor-Leste, and postrevolution in Tunisia. In addition, the report proposes a conceptual framework to understand how ICTs can contribute to improving service delivery and assisting with nation-building. The opening chapter of the report gives an overview of the relationship between confl ict, reconstruction, and the role of ICTs. It builds on experience within the Bank as well as on a wide range of practitioner, academic, and other literature. The second chapter seeks to establish a framework for understanding the ways in which ICTs interact with societies in transition from violence to stability, and for leveraging their potential to further that transition. The roots of this lie in understanding two fields of study, policy and practice: - Analysis of confl ict and post-confl ict reconstruction, and - Analysis of ICTs and the development of an information society. Chapter three then analyses the relationship between these two fi elds and proposes a framework for analysis and policy development. The fourth chapter makes a number of recommendations to the World Bank Group, to other donors and development actors, as well as to the governments of countries emerging from violent confl ict, and suggests areas for further research.
