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.

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.

Описание: Handbook on ICT in Developing Countries: Next Generation ICT Technologies is the second volume of the Handbook of ICT in Developing Countries series. The first volume was on the potential implementation and service delivery of the forth-coming 5G networks. Here the focus is on the new technologies and services enabled by 5G networks or broadband Internet networks including artificial Intelligence (AI), machine learning, augmented reality, Internet of Things (IoT), autonomous driving, blockchain solutions, cloud solutions etc. Some of these are already globally experiencing growth in the existing networks and all of them are expected to grow substantially in the future. Examples: currently, 5% of global organizations have fully adopted AI, but the penetration is expected to increase rapidly before 2025. IoT with 20.35 billion devices connected in 2017 is estimated to show 75.44 billion devices connected in 2025. The expected growth is based on delivering of new value to businesses and citizens. It is, however, not obvious that this growth will also occur in developing countries. Currently, the digital divide between developing countries and developed countries is widening. This is mostly due to the lack of infrastructure and low level of awareness by the businesses and citizens of the value made possible by the new technologies for developing countries. The book discusses the potentials of the new technologies for developing countries and the need for market interventions that will facilitate the demand and supply side of the market. It is designed for a broad audience including practitioners, researchers, academics, policy makers and industry players and influencers. The language and approach to the handbook is a combination of the academic writing style and professional reviews.

Описание: THE SERIES: INTELLIGENT BIOMEDICAL DATA ANALYSIS By focusing on the methods and tools for intelligent data analysis, this series aims to narrow the increasing gap between data gathering and data comprehension. Emphasis is also given to the problems resulting from automated data collection in modern hospitals, such as analysis of computer-based patient records, data warehousing tools, intelligent alarming, effective and efficient monitoring. In medicine, overcoming this gap is crucial since medical decision making needs to be supported by arguments based on existing medical knowledge as well as information, regularities and trends extracted from big data sets.
