This book was released on 2015-02-13 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Buildings, trees, and terrain represent main local sources of propagation impairment in land mobile satellite (LMS) propagation. These elements interact with wave propagation through reflection, scattering and diffraction. Thus it is very important to characterize their effects on the radio channel. Accurate characterization is crucially needed to optimize system parameters such as power link budget, fading margin and hand-off algorithm. At mobile satellite frequencies roadside buildings can be assumed as conduction objects that significantly block the propagating signal. Even with existence of a direct path from the satellite to the mobile, the reflection and scattering processes lead to other viable wave paths. These multipath signals interfere with each other, leading to a rapid fading effect. Hence, building blockage is one of the most important problems for satellite mobile radio channels. This book developed a model to characterize the effect of building blockage on LMS channel. The model is used to measure the influence of building blockage in term of fading, inter-symbol interference, bit error rate and depolarization.

Book excerpt: Mobile systems operate in a variety of different scenarios. These include remote rural areas, where the terrain is irregular, dense urban areas where buildings dominate, and even inside those buildings. Equipment can either be carried by pedestrians or be in a high-speed vehicle or train. Various alternative methods of predicting the mean signal strength and its variability are surveyed and their applicability to a particular situation is discussed. Ray-tracing methods are introduced in connection with indoor propagation. Multipath, probably the single most destructive influence on mobile syst.
Download or read book Radio Wave Propagation and Channel Modeling for Earth Space Systems written by Athanasios G. Kanatas and published by CRC Press. This book was released on 2017-12-19 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accurate design of earth–space systems requires a comprehensive understanding of the various propagation media and phenomena that differ depending on frequencies and types of applications. The choice of the relevant channel models is crucial in the design process and constitutes a key step in performance evaluation and testing of earth–space systems. The subject of this book is built around the two characteristic cases of satellite systems: fixed satellites and mobile satellite systems. Radio Wave Propagation and Channel Modeling for Earth–Space Systems discusses the state of the art in channel modeling and characterization of next-generation fixed multiple-antennas and mobile satellite systems, as well as propagation phenomena and fade mitigation techniques. The frequencies of interest range from 100 MHz to 100 GHz (from VHF to W band), whereas the use of optical free-space communications is envisaged. Examining recent research advances in space-time tropospheric propagation fields and optical satellite communication channel models, the book covers land mobile multiple antennas satellite- issues and relative propagation campaigns and stratospheric channel models for various applications and frequencies. It also presents research and well-accepted satellite community results for land mobile satellite and tropospheric attenuation time-series single link and field synthesizers. The book examines aeronautical communications channel characteristics and modeling, relative radio wave propagation campaigns, and stratospheric channel model for various applications and frequencies. Propagation effects on satellite navigation systems and the corresponding models are also covered.

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.
