Available in PDF, EPUB and Kindle. Book excerpt: Radio Wave Propagation: Consolidated Summary Technical Report of the Committee on Propagation of the National Defense Research Committee presents all the scientific information and report of experiments. This book discusses the problems encountered in the propagation of radio waves. Organized into three volumes, this book begins with an overview of the technical developments in the study of tropospheric propagation. This text then outlines the general theory of standard and nonstandard propagation together with descriptions and results of transmission experiments designed to test the theory. Other chapters consider the more unusual problems concerning the radar behavior of targets. This book discusses as well the problems of radio wave propagation in the standard atmosphere at frequencies above 30 megacycles. The final chapter deals with the selection and utilization of local terrain features that affect propagation and the performance of equipment. This book is a valuable resource for scientists and engineers in the field of radio wave propagation.

Available in PDF, EPUB and Kindle. Book excerpt: While there are numerous books describing modern wireless communication systems that contain overviews of radio propagation and radio channel modelling, there are none that contain detailed information on the design, implementation and calibration of radio channel measurement equipment, the planning of experiments and the in depth analysis of measured data. The book would begin with an explanation of the fundamentals of radio wave propagation and progress through a series of topics, including the measurement of radio channel characteristics, radio channel sounders, measurement strategies, data analysis techniques and radio channel modelling. Application of results for the prediction of achievable digital link performance would be discussed with examples pertinent to single carrier, multi-carrier and spread spectrum radio links. This work would address specifics of communications in various different frequency bands for both long range and short range fixed and mobile radio links.

Available in PDF, EPUB and Kindle. Book excerpt: Statistical Methods in Radio Wave Propagation contains the proceedings of a symposium held at the University of California, Los Angeles, on June 18-20, 1958. The papers explore the use of statistical techniques in the analysis and interpretation of data pertaining to the propagation of radio waves. The discussion is organized around three themes: statistical theory and methodology; radio propagation phenomena having a joint statistical and physical structure; and instrumentation. This book is comprised of 23 chapters and begins by summarizing the principal results of a series of statistical studies on the intensity distributions due to rapid fading. The reader is then introduced to some theoretical investigations on fading phenomena; radio-measurement of ionospheric drift as a problem in parameter estimation; the propagation of random radiation in free space; and the statistics of working spells and periods of breakdown for a number of radio links in series. The remaining chapters deal with airborne measurements of tropospheric index of refraction fluctuations; the distribution of the fade lengths of a randomly fading radio signal; diversity statistics in scatter propagation; and extrapolation of spatial correlation functions. The final chapter describes a rapid statistical data processing system for radio propagation research. This monograph will be a useful resource for both radio scientists and statisticians.

Available in PDF, EPUB and Kindle. Book excerpt: Propagation of Radio Waves at Frequencies Below 300 KC/S covers the proceedings of the Seventh Meeting at the AGARD Ionospheric Research Committee, held in Munich, Germany on September 17-21, 1962. This book is organized into eight parts encompassing 32 chapters. The first parts deal with research studies concerning the electron density distribution and some properties of the lower ionosphere, as well as the effect of D-layer irregularities on radio wave propagation. The next parts explore the low frequency propagation in the lower ionosphere, the measurement of oblique incidence, and the statistical frequency spectrum of radio noise below 300 kc/s. The remaining chapters discuss the diurnal changes, the statistical prediction, the mode theory, and the propagation of very and extremely low frequency radio waves in the ionosphere. These chapters also examine the Earth resonance. This book will prove useful to astronomers, astrophysicists, and space scientists.

Download or read book The Propagation of Radio Waves written by K. G. Budden and published by Cambridge University Press. This book was released on 1988-08-04 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with the ionosphere and the magnetosphere, and the theory of their effect on radio waves. It includes accounts of some mathematical topics now widely used in this study, particularly W. K. B. approximations, Airy integral functions and integration by steepest descents. The subject is divided into ray theory and full wave theory. Ray theory is useful for high frequencies when the ionosphere is treated as a horizonally stratified medium. The discussion of the magnetosphere, whose structure is more complicated, includes an account of whistlers and ion cyclotron whistlers. The book has been planned both for final year undergraduates and as a reference book for research. It is suitable as a course book on radio propagation for students of physics or electrical engineering or mathematics. Some of the topics are presented from an elementary viewpoint so as to help undergraduates new to the subject. The later parts are more advanced. Because the subject is so large and has seen many important recent advances, some topics have had to be treated briefly, but there is a full bibliography with about 600 references.
Download or read book Radio Wave Propagation for Telecommunication Applications written by Hervé Sizun and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the physical mechanisms involved in the propagation of electromagnetic waves in the radiofrequency range, inside and outside buildings, in the terrestrial and near space environments, with a special focus on mobile radio communication. It combines a theoretical and an experimental approaches with an understanding of the physical environment through adequate formulations of the laws of electromagnetism. It should thus provide the background needed by advanced students and development engineers for the conception of high quality and reliable telecommunication systems.
Download or read book Results of Radio propagation Experiments Conducted During the Total Solar Eclipse of 20 July 1963 written by Stanley J. SCHMIDT and published by . This book was released on 1965 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of radio-wave propagation experiments were conducted during the total solar eclipse of 20 July 1963 to measure its effect on the ionosphere. Receivers monitoring selected optimumly located standard radio broadcast stations and riometers indicating the level of cosmic noise were operated at Copper Center, Alaska, and Jefferson, Maine. A sweep-frequency receiver covering the entire standard broadcast band was also operated at the Maine site during the eclipse. Conclusive proof was obtained that the eclipse did affect propagation conditions at the frequencies utilized for standard broadcasting. Out of a total of eighteen broadcast stations monitored, located at intervals between 560 and 1570 kc/s, the increase in the received signal strengths of seventeen stations ranged from 7.5 to 37 dB. All observed signal variations are asymmetrical with respect to the time of on-the-ground totality. There is a threshold phenomenon evident as the increases in signal strength occurred only when the majority of the sun's radiation was cut off. The riometer operated in Alaska indicated a maximum increase of one-half dB in the level of cosmic noise at 30 Mc/s. The change in cosmic-noise level occurred simultaneously with the beginning of the eclipse, increased to a maximum at ionospheric totality, and returned to normal at last contact. (Author).
