Book excerpt: Excerpt from Zonal Harmonics in Low Frequency Terrestrial Radio Wave Propagation An improved definition of the reflection coefficient matrix is presented which accounts for the reflection process in a manner which can be justified both mathematically and physically. In fact, the entire reflection coefficient matrix for the anisotropic ionosphere can be retained as a variable of the zonal harmonic summation process with resultant improvement in computation accuracy. Demonstrative compu tations indicate considerable advantage in the method as an alternate approach to the propagation problem. Key Words: Extra low frequencies, geometric -optics, geometric series, lf, vlf, elf mode theory, low frequencies.

Available in PDF, EPUB and Kindle. Book excerpt: The various forms of the solution of Maxwell's equations for the propagation of low frequencies in the waveguide between a spherical earth and a concentric ionosphere are given in concise form. A tutorial discussion is given of the various solutions to acquaint experimenters with the practical techniques which are available. An important feature of all the solutions given is the accommodation of the effect of the effect of the variation with height of the electrical properties of the upper boundary (ionosphere). The forms of the waveguide solution include the zonal harmonics series for the total field, the mode sum and the geometric (wavehop) series. The connections between the various forms are clearly shown. The discussion is illustrated by sample calculations of the geometric series type solution for normal day and night.

Download or read book Introduction to RF Propagation written by John S. Seybold and published by John Wiley & Sons. This book was released on 2005-10-03 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to RF propagation that spans all wireless applications This book provides readers with a solid understanding of the concepts involved in the propagation of electromagnetic waves and of the commonly used modeling techniques. While many books cover RF propagation, most are geared to cellular telephone systems and, therefore, are limited in scope. This title is comprehensive-it treats the growing number of wireless applications that range well beyond the mobile telecommunications industry, including radar and satellite communications. The author's straightforward, clear style makes it easy for readers to gain the necessary background in electromagnetics, communication theory, and probability, so they can advance to propagation models for near-earth, indoor, and earth-space propagation. Critical topics that readers would otherwise have to search a number of resources to find are included: * RF safety chapter provides a concise presentation of FCC recommendations, including application examples, and prepares readers to work with real-world propagating systems * Antenna chapter provides an introduction to a wide variety of antennas and techniques for antenna analysis, including a detailed treatment of antenna polarization and axial ratio; the chapter contains a set of curves that permit readers to estimate polarization loss due to axial ratio mismatch between transmitting and receiving antennas without performing detailed calculations * Atmospheric effects chapter provides curves of typical atmospheric loss, so that expected loss can be determined easily * Rain attenuation chapter features a summary of how to apply the ITU and Crane rain models * Satellite communication chapter provides the details of earth-space propagation analysis including rain attenuation, atmospheric absorption, path length determination and noise temperature determination Examples of widely used models provide all the details and information needed to allow readers to apply the models with confidence. References, provided throughout the book, enable readers to explore particular topics in greater depth. Additionally, an accompanying Wiley ftp site provides supporting MathCad files for select figures in the book. With its emphasis on fundamentals, detailed examples, and comprehensive coverage of models and applications, this is an excellent text for upper-level undergraduate or graduate students, or for the practicing engineer who needs to develop an understanding of propagation phenomena.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Based on the popular Artech House classic, Digital Communication Systems Engineering with Software-Defined Radio, this book provides a practical approach to quickly learning the software-defined radio (SDR) concepts needed for work in the field. This up-to-date volume guides readers on how to quickly prototype wireless designs using SDR for real-world testing and experimentation. This book explores advanced wireless communication techniques such as OFDM, LTE, WLA, and hardware targeting. Readers will gain an understanding of the core concepts behind wireless hardware, such as the radio frequency front-end, analog-to-digital and digital-to-analog converters, as well as various processing technologies. Moreover, this volume includes chapters on timing estimation, matched filtering, frame synchronization message decoding, and source coding. The orthogonal frequency division multiplexing is explained and details about HDL code generation and deployment are provided. The book concludes with coverage of the WLAN toolbox with OFDM beacon reception and the LTE toolbox with downlink reception. Multiple case studies are provided throughout the book. Both MATLAB and Simulink source code are included to assist readers with their projects in the field.
