Download or read book Modern Communications Jamming Principles and Techniques written by Richard Poisel and published by Artech House. This book was released on 2011 with total page 895 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edition features a wealth of new material on urban warfare, including a computer simulation of EW architecture alternatives for land-based forces based on urban constraints. It also includes an expanded section on time-hopped spread spectrum communications, more details on modern communication system technologies such as CDMA and OFDM, and an in-depth discussion on sources of urban noise. This practical resource is focused on showing the reader how to design and build jammers specifically targeted at spread spectrum, anti-jam communications. Moreover, it gives assistance in evaluating the expected performance of jamming systems against modern communications systems, and discover the best waveform to use to counter communication systems designed to be effective in jamming environments. While mathematical derivations in general are avoided, the book presents error rate performance equations for most modern digital anti-jam communication systems

Download or read book Radio System Design for Telecommunications written by Roger L. Freeman and published by John Wiley & Sons. This book was released on 2006-11-03 with total page 912 pages. Available in PDF, EPUB and Kindle. Book excerpt: Step-by-step tutorial to master current design techniques for wireless communication systems The Third Edition of Radio System Design for Telecommunications brings this highly acclaimed book fully up to date with the latest technological advances and new applications. At the same time, the hallmarks of the previous editions, including the text's popular tutorial presentation, have been retained. Readers therefore get all the tools and guidance they need to master an essential set of current design techniques for radio systems that operate at frequencies of 3 MHz to 100 GHz. Using simple mathematics, the author illustrates design concepts and applications. The book's logical organization, beginning with a discussion of radio propagation problems, enables readers to progressively develop the skills and knowledge needed to advance in the text. Topics that are new to the Third Edition include: Chapter devoted to wireless LANs (WLANs) as detailed in IEEE 802.11 Subsections covering IEEE 802.15, 802.16, 802.20, and the wireless metropolitan area network (WMAN) WiFi, WiMax, and UWB applications that have recently experienced explosive growth Broadband radio in telecommunications, as well as offset frequency division multiplex (OFDM), a new technique for transmitting information in an interference environment The use of very small aperture satellite terminal (VSAT) systems as an economical alternative to public switched telecommunication networks (PSTN) Review questions and problems at the end of each chapter engage readers' newfound skills and knowledge and help them assess whether they are ready to progress to the next chapter. References are provided for readers who want to investigate particular topics in greater depth. Students in wireless telecommunications will find the book's tutorial style ideal for learning all the ins and outs of radio system design, whereas professionals in the industry will want to refer to the Third Edition for its clear explanations of the latest technology and applications.

Download or read book Tactical Communications for the Digitized Battlefield written by Michael J. Ryan and published by Artech House. This book was released on 2002 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional tactical communications systems consist of a number of separate subsystems with little interworking between them and with external sensors and weapons systems. Combat net radio (CNR) has provided the high-mobility communications required by combat troops, while trunk communications systems have provided high-capacity communications between headquarters at the expense of mobility. The focus of this book is on new, information-age technologies that promise to offer seamless integration of real-time data sharing, creating a single logical network architecture to facilitate the movement of data throughout the battlespace. Because the structure of this network is constrained by the fundamental trade-off between range, mobility and capacity that applies to all communications systems, this network is unlikely to be based on a single network technology. This book presents an architecture for this network, and shows how its subsystems can be integrated to form a single logical network.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this final Bachelor's degree project is to design and study the relia-bility of a transoceanic shortwave radio link that connects London and New York. Two ofthe most important stock exchanges of the world are located in these two cities and theconnection between them is currently done through submarine optical fibers.In the last few years, with the automation of the stock market activity (a trend that is alsoknown as High Frequency Trading), several companies have begun to look for alternativesto optical fiber to reduce the latency of the link use this advantage to be more competi-tive. However, before designing the radio link, the behaviour of the ionosphere has beenstudied to correctly understand how ionospheric propagation works and what factors cancompromise the communication.The radio link design is based on the choice of different aspects such as the location of thestations, the type of antenna, the protocol or the propagation mode, among others. Thisselection has been made prioritizing the reliability of the link over other aspects such asthe capacity or the bandwidth.Once these aspects have been decided, the communication has been studied using anionospheric propagation prediction software called VOACAP. This software gives us veryrelevant information about the reliability or the power received. This will allow us to modelthis propagation by relating the behaviour of the different frequency bands with the varia-tions suffered by the ionosphere during the different months of the year and the differenthours of the day.On the other hand, this study demonstrates how the designed radio link substantially re-duces the latency of the fiber optic with a high reliability that can allow its use regularly.
