Описание: With design optimization as a key focus, this book covers both antenna fundamentals and microstrip antenna. It includes a section on antenna theory that introduces two kinds of elementary linear sources, Huygen’s planar element, and also the analysis and synthesis of the discrete and continuous arrays formed by these elementary sources. In addition, it introduces the digital beam-forming antenna and smart antenna. The section on microstrip antenna discusses the cavity mode theory and also covers some related issues including the design of irregularly shaped patches and the analysis of mutual coupling. With several effective design approaches covered, this book can serve as either a textbook or a self-study book.
Описание: In recent years, antenna technologies have received a renewed interest because of the rapid development of wireless devices and advanced defense applications. Consequently, highly accurate and efficient modeling and simulation tools are needed to satisfy the demand for sophisticated antenna designs. This book covers all the technical aspects in the analysis of complex antennas and arrays using the finite element method.

Описание: Cylindrical arrays lie at the heart of the antenna systems of most major radio communication systems, including broadcasting networks, cellular 'phone systems and radar. In this book, the authors present practical theoretical methods for determining current distributions, input admittances and field patterns of a wide variety of cylindrical antennas, including the isolated antenna, the two-element array, the circular array, curtain arrays, Yagi and log-periodic arrays, planar arrays and three-dimensional arrays. Coverage includes analysis of horizontal antennas over, on and in tharth and sea, large resonant arrays of electrically short dipoles and a chapter on the theory and techniques of experimental measurement. Written by three of the leading engineers in the field, and based on world-class research carried out at Harvard over the last 40 years, Cylindrical Antennas and Arrays is destined to become established as the basic reference for practising engineers and advanced students for many years to come.

Описание: Reflects the developments in engineering and design of antennas. This work gives you the expertise you need to solve various kinds of engineering problems that may arise in the design and application of different types of antenna`s.
Описание: A complete examination of traditional and new advanced antennas used in the automotive industry, this book provides information taken from designs published in technical and academic papers, patents, and pending patents. Highlighting the practical aspects of antenna design, the authors describe the entire design process, starting with the antenna simulation, prototype sample fabrication, and laboratory test measurements, and finishing with test measurements in the real environment. The book includes simulation examples of antenna parameters that significantly speed up the design process using software packages such as FEKO, NEC, IE3D, and Genesys.
Описание: "Wireless Communications over MIMO Channels: Applications to CDMA and Multiple Antenna Systems" covers both, state of the art channel coding concepts
and CDMA and multiple antenna systems, rarely found in other books on the subject. Furthermore, an information theoretical analysis of CDMA and SDMA systems illuminate ultimate
limits and demonstrates the high potential of these concepts. Besides spatial multiplexing, the use of multiple transmit antennas in order to increase the link reliability by diversity concepts
(space time coding) is described.
Another focus is the application of error control coding in mobile radio communications. Accompanying appendices include: basic
derivations, tables of frequently used channel models, chain rules for entropy and information, data processing theorem, basics of linear algebra, Householder reflection and Givens
rotation, and the LLL algorithm for lattice reduction.
Описание: Embedded systems applications that are either mission or safety-critical usually entail low- to mid- production volumes, require the rapid development of specific tasks, which are typically computing intensive, and are cost bounded. The adoption of re-configurable FPGAs in such application domains is constrained to the availability of suitable techniques to guarantee the dependability requirements entailed by critical applications. This book describes the challenges faced by designers when implementing a mission- or safety-critical application using re-configurable FPGAs and it details various techniques to overcome these challenges. In addition to an overview of the key concepts of re-configurable FPGAs, it provides a theoretical description of the failure modes that can cause incorrect operation of re-configurable FPGA-based electronic systems. It also outlines analysis techniques that can be used to forecast such failures and covers the theory behind solutions to mitigate fault effects. This book also reviews current technologies available for building re-configurable FPGAs, specifically SRAM-based technology and Flash-based technology. For each technology introduced, theoretical concepts presented are applied to real cases. Design techniques and tools are presented to develop critical applications using commercial, off-the-shelf devices, such as Xilinx Virtex FPGAs, and Actel ProASIC FPGAs. Alternative techniques based on radiation hardened FPGAs, such as Xilinx SIRF and Atmel ATF280 are also presented. This publication is an invaluable reference for anyone interested in understanding the technologies of re-configurable FPGAs, as well as designers developing critical applications based on these technologies.
Описание: This book provides, for the first time, a single complete reference on microphone arrays. Top researchers in this field contributed articles addressing their specific topics of study. The results cover the current state of the art in microphone array research, development, and technological application. Part I concerns the problem of enhancing the speech signal acquired by an array of microphones. Part II is devoted to the source localization problem. Part III details some specific applications of microphone array technology available today. Part IV presents expert summaries of current open problems in the field, as well as personal views of what the future of microphone array processing might hold. The individual chapters selected for the book were designed to be tutorial in nature with a specific emphasis on recent important results. They are of utility to a large audience, from the student or practising engineer just approaching the field to the experienced researcher.
