Описание: The Information Super Highway concept has gained much popularity and can be realised by using optical fibres. This book sets out the necessary technology to build the super highway.
Описание: This book is written as an academic textbook aimed at final year undergraduate or postgraduate engineers. The book will cover all aspects of digital video broadcasting and will be divided into three main sections: VIDEO The amount of data required to represent an analog video signal in digital form is enormous. This section will describe the signal processing tools which are used to compress this data to a more manageable amount. This will lead to a detailed description of the Moving Picture Experts' Group (MPEG) standard MPEG-2 which is at the heart of all digital video broadcasting services. AUDIO The volume of data when analog audio is digitized is also very large. Here again signal processing techniques can be used to significantly reduce the total volume of data. The signal processing tools which achieve this will be described as will the two major standards (MPEG-2 Advanced Audio Coding and Dolby AC-3) which will be used internationally in digital video broadcasting systems. SYSTEMS Considered here are the systems aspects of digital video broadcasting. This included the systems layer proposed by MPEG, modulation and transmission, forward error correction, datacasting, conditional access and digital storage media command and control. The various chapters in the book will be supported by appropriate examples given in MATLAB. As well as problems at the end of each chapter, a number of exercises will be presented to allow students to implement the various techniques using MATLAB. This approach ensures that students obtain a deep understanding of the topics covered.
Описание: Covering new advances, theories, and techniques, this book reflects the range of questions being posed about post-production 3D mastering, delivery options, and home screens. Each chapter deals with a different stage of an end-to-end 3DTV system, including capture, representation, coding, transmission, and display. Discussing theory and application, the text covers stereoscopic and autostereoscopic techniques—the latter eliminating the need for special glasses and allowing for viewer movement. It also examines emerging holographic approaches, which have the potential to provide the truest three-dimensional images.
Описание: Written and edited by experts who have developed WiMAX technology and standards WiMAX, the Worldwide Interoperability for Microwave Access, represents a paradigm shift in telecommunications technology.

Описание: Opportunities are at hand for professionals eager to learn and apply the latest theories and practices in air interface technologies. Written by experienced researchers and professionals, LTE-Advanced Air Interface Technology thoroughly covers the performance targets and technology components studied by 3GPP for LTE-Advanced. Besides being an explanatory text about LTE-Advanced air interface technology, this book exploits the technical details in the 3GPP specification, and explains the motivation and implication behind the specifications. After a general description of wireless cellular technology evolution and the performance targets and major technical features of LTE-Advanced, LTE-Advanced Air Interface Technology discusses various innovative technical features in detail, including Innovative concepts in carrier aggregation techniques Collaborative multipoint (CoMP) theory and performance analysis Enhanced multiantenna solutions or multiple-input, multiple-output (MIMO) technology, in particular, multiuser and multilayer MIMO Relaying issues Self-organizing and heterogeneous networks Interference suppression and enhanced intercell interference coordination (eICIC) technology This book opens the door of LTE-A technology for practitioners in any stage of wireless communications. Beginning with basic communication principles, the book demonstrates how a complete wireless theory is built. Readers can work independently on original case studies and simulation programming examples, with an emphasis on technology and performance. Designed for professionals interested in gaining an upper hand, this book is the ideal educational and informative resource in the emerging field of air interface technology.
Описание: Jeffrey James is one of the relatively few academics to have systematically taken on the topic of IT and development. In this timely book he undertakes a methodological critique of prominent topics in the debate. Challenging the existing literature by international and governmental institutions, the book looks not only at the digital divide but also at issues such as digital preparedness, leapfrogging and low-cost computers. James also raises important issues which have been largely neglected in the literature, such as the implications for poverty in developing countries and the macroeconomics of mobile phones. The book argues that benefits from IT are captured in a different form in developing as opposed to developed countries. In the latter, gains come from technology ownership and use, whereas in the former, benefits cannot be captured as much in this way because ownership is more limited. Interestingly, the author shows that developing countries have responded to this distinction with a series of local innovations which are often low-cost and pro-poor. This finding contradicts the widely held view that poor countries are unable to generate major innovations within their own borders. Accessible and clearly written, this book will be of great interest to scholars of development economics and development studies, and is relevant to both policy-makers and academics.
