LEARN DCN data communication and computer network

LANs are composed of inexpensive networking and routing equipment. It may contains local servers serving file storage and other locally shared applications. It mostly operates on private IP addresses and does not involve heavy routing. LAN works under its own local domain and controlled centrally. LAN uses either Ethernet or Token-ring technology. Ethernet is most widely employed. LAN technology and uses Star topology, while Tokenring is rarely seen. LAN can be wired, wireless, or in both forms at once.

Digital Communications

Digital Communications is a classic book in the area that is designed to be used as a senior or graduate level text. The text is flexible and can easily be used in a one semester course or there is enough depth to cover two semesters. Its comprehensive nature makes it a great book for students to keep refer to in their professional careers.This best-selling book in Digital Communications by John G. Proakis has been revised to reflect the current trends in the field. Some of the topics that have been added include Turbocodes, Antenna Arrays, Iterative Detection, and Digital Cellular Systems. Also new to this edition are electronic figures for presentation materials found on the website.

High-Speed Wireless Communications. Ultra-wideband, 3G Long Term Evolution, and 4G Mobile Systems

Analyzing and designing reliable and fast wireless networks requires an understanding of the theory supporting these systems and the engineering complexities of their implementation. This volume describes the underlying principles and major applications of high-speed wireless technologies, with emphasis on ultra-wideband (UWB) wireless systems, 3G long term evolution, and 4G mobile networks. Key topics such as cross-layer optimization are discussed in detail and various forms of UWB are covered. Recent research developments are described before identifying the scope and direction for future research. Covering the latest technologies in the area, this book will be a valuable resource for graduate students of electrical and computer engineering as well as practitioners in the wireless communications industry.

Digital Interfaces and Bus Systems for Communication. Practical Fundamentals

Digital communication confronts us every day in modern process engineering:- it is used for configuring and setting the parameters for microprocessor instruments- serial bus systems, with minimum wiring requirements, are able to acquire a large amount of decentralized information and distribute it to the process equipment. Intelligent field and automation devices can communicate directly with one another via a digital bus.This book is intended as a step-by-step introduction to the subject of digital communications, for practical engineers and those new to this field. The emphasis is on clarifying generalized topics, as well as including some JUMO-specific applications.In this revised edition, the material on bus systems has been extensively updated. The method of operation of bus systems for which JUMO has field devices available is explained in a practical manner.Special thanks are due to all our colleagues, who helped us to prepare this book with their cooperation and professional input.

Advanced Mobile Communications. Inner Physical Layer Transceiver, Volume 1

This book is an extensively elaborated treatise on physical layer concepts of advanced mobile communications. Setting out from the author's own experience of university teaching for over three decades, the book covers the most fundamental aspects of physical layer transceivers for mobile communications ranging from approximation schemes such as sampling, the Fourier series and the Fourier transformation over multi-antenna techniques including aspects of curvilinear coordinate systems, tensor calculus, determinant computation rules, array antennas, spatial sampling, details on probability theory and information theory, optimum detection with soft outputs and spatial multiplexing to orthogonal frequency division multiplexing.

Sensor and Data Fusion

The methods provided by sensor and data fusion [14] are important tools for fusing large sets of mutually complementary data end efficiently exploiting the sensor systems available. A challenging exploitation technology at the common interface between sensors, command & control systems, and the human decision makers involved, this technology plays a key role in applications with time-critical situations or in situations with a high decision risk, where human deficiencies are to be compensated by automatically or interactively working fusion techniques (compensating decreasing attention in routine situations, focusing the attention on anomalous or rare events, complementing limited memory, reaction, or combination capabilities of human beings). Besides the advantages of reducing the human work load in routine or mass tasks, data fusion from mutually complementary information sources can well produce qualitatively new knowledge that otherwise would remain unrevealed.
