Описание: The Internet revolution. Once, the public was delighted with 14.4 modem access and fascinated by low-tech Web site content. But not for long.
Technology has raced to keep up with users' calls for high-speed facilities and advanced applications. With the development of high-speed transmission media and the availability of
high-speed hardware, we are fast approaching the day when a single communication network will support all communication activities - and that network will use optical fibers as its
transmission media and optical switch/routers as its nodes. "The Handbook of Optical Communication Networks" presents comprehensive, up-to-date technical information on
integrated, state-of-the-art optical networks.
Beginning with an in-depth introduction to the field, top international authorities explore every major aspect of optical networks,
from basic concepts to research grade material. Their discussions cover all of the essential topics, including protocols, resource management, routing and wavelength
assignment in WDM networks, connection management, survivability, enabling technologies, and future trends.To meet the remaining technical and implementation challenges of
optical networks, present and future communications professionals need a convenient, one-stop source for the relevant fundamentals, technical details, and applications. "The
Handbook of Optical Communication Networks" provides that information in a presentation that is structured for fast access, organized for optimum utility, and packed with the insights
of true leaders in the field.
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.

The Work, originally published as Volume 30, Numbers 1-3 of the Journal of VLSI Signal Processing Systems for Signal, Image, and Video Technology, will be valuable to anyone working or researching in the field of wireless communication systems. It serves as an excellent reference, providing insight into some of the most challenging issues being examined today.
Описание: Well over a billion people are currently using cellular telephones, and this number is expected to grow to over two billion in the next few years. It is remarkable that a device that was considered a high-technology "toy" just a few years ago is now an indispensable feature of modern life. One of the key reasons for this remarkable transformation is the integration of all the radio functions of a cellular telephone onto a single inexpensive piece of silicon. This achievement is a result of innovations in design and process technology that allowed formerly discrete and separate devices to be integrated onto a common substrate. Now that this integration has been accomplished, the next challenge is to make these radio functions adaptive to their environment. This "adaptive" feature of wireless communications devices is just today becoming a reality, and Adaptive Low-Power Circuits for Wireless Communications represents one of the first comprehensive treatments of the subject. Adaptive radio transceivers require a comprehensive theoretical framework in order to optimize their performance. Adaptive Low-Power Circuits for Wireless Communications provides this framework with a discussion of joint optimization of Noise Figure and Input Intercept Point in receiver systems. Original techniques to optimize voltage controlled oscillators and low-noise amplifiers to minimize their power consumption while maintaining adequate system performance are also provided. The experimental results presented at the end of the book confirm the utility of the proposed techniques.

Описание: Detailing a systems approach, Optical Wireless Communications: System and Channel Modelling with MATLAB®, is a self-contained volume that concisely and comprehensively covers the theory and technology of optical wireless communications systems (OWC) in a way that is suitable for undergraduate and graduate-level students, as well as researchers and professional engineers. Incorporating MATLAB® throughout, the authors highlight past and current research activities to illustrate optical sources, transmitters, detectors, receivers, and other devices used in optical wireless communications. They also discuss both indoor and outdoor environments, discussing how different factors—including various channel models—affect system performance and mitigation techniques. In addition, this book broadly covers crucial aspects of OWC systems: Fundamental principles of OWC Devices and systems Modulation techniques and schemes (including polarization shift keying) Channel models and system performance analysis Emerging visible light communications Terrestrial free space optics communication Use of infrared in indoor OWC One entire chapter explores the emerging field of visible light communications, and others describe techniques for using theoretical analysis and simulation to mitigate channel impact on system performance. Additional topics include wavelet denoising, artificial neural networks, and spatial diversity. Content also covers different challenges encountered in OWC, as well as outlining possible solutions and current research trends. A major attraction of the book is the presentation of MATLAB simulations and codes, which enable readers to execute extensive simulations and better understand OWC in general.

Описание: This monograph summarizes the special functions needed in the performance analysis of wireless communications systems.On the basis of special Gaussian and Owen functions, the methodology for the calculation of the relationship for symbol and bit error probabilities with coherent reception, for the two-dimensional multi-positional signal constructions in communications channel with deterministic parameters and additive white Gaussian noise (AWGN), was developed. To explain the concepts, examples are provided after the mathematical proofs to illustrate how the theorems could be applied; this includes symbol and bit error probability formulas receiving for present signal constructions (QAM, PSK, APSK and HEX), and error probability dependencies from signal-to-noise ratio (SNR).There are many books in communications theory dealing with several topics covered in this monograph, but none has consolidated all error probability calculations in a single book. This book therefore serves a very niche area.This text is written for graduate students, researchers, and professionals specializing in wireless communications and electrical engineering; dealing with probability and statistics, approximation, and analysis & differential equations.
