Available in PDF, EPUB and Kindle. Book excerpt: The possibility of detecting communication systems which use signals scattered by meteor trails, and intercepting information passed over such systems is discussed. To obtain the statistical data required on the fraction of meteor trails that scatter energy to an intercept location, and the fraction of transmitted messages that can be intercepted, a computation program is formulated. For a specified distribution of meteor sources, the fraction of the meteor trails that will scatter a signal to any point in a large area about the transmitter, and the fraction of message fragments received that can be intercepted at any point in the region about a receiver location, can be readily found. The computed results for a uniform distribution of meteor sources across the sky are displayed graphically. An example is worked out showing that the data can be used to estimate the performance of a meteor-scatter communications link. Sample computations on the probability of detecting the operation of a meteor-burst communications system are carried out. Finding the locations of transmitters using meteor-scatter signals, recognition of operating characteristics, and the interception of information passed over such links are also discussed. (Author).

Download or read book Meteor Burst Communications written by Donald L. Schilling and published by Wiley-Interscience. This book was released on 1993-04-12 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores the meteor burst channel. Leading experts in the communications field cover the research, military and commercial applications of this subject. Following an introduction to the technology, early chapters describe this channel, the theory and modeling techniques used to simulate it and the use of variable data rate transmission for efficient communication. Later chapters present a method for implementing such a system using FM techniques, compare experimental results with theory, offer additional theoretical results obtained for the variable data rate techniques and discuss the improvement obtained through the use of forward error correction coding.

This book was released on 1961 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bibliography constitutes the second in a series of four or five being prepared by Meteorological Abstracts for the Boulder Laboratories of the National bureau of Standards. The general subject area of these compilations in propagation of electromagnetic (radio) waves in the atmosphere. The present bibliography consists of 368 abstracts on meteor trail propagation, arranged alphabetically by author and including articles dating from the earliest studies by Nagaoka (B-245) in 1929 on the effect of meteoric ionization on radio communications, to the numerous papers reflecting the recent emphasis on meteor burst communication. No material published after 1960 has been included.

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.
