Available in PDF, EPUB and Kindle. Book excerpt: An accessible student-oriented approach to radiowave propagation Propagation-the process whereby a signal is conveyed between transmitter and receiver-has a profound influence on communication systems design. Radiowave Propagation provides an overview of the physical mechanisms that govern electromagnetic wave propagation in the Earth's troposphere and ionosphere. Developed in conjunction with a graduate-level wave propagation course at The Ohio State University, this text offers a balance of physical and empirical models to provide basic physical insight as well as practical methods for system design. Beginning with discussions of propagation media properties, plane waves, and antenna and system concepts, successive chapters consider the most important wave propagation mechanisms for frequencies ranging from LF up to the millimeter wave range, including: Direct line-of-sight propagation through the atmosphere Rain attenuation The basic theory of reflection and refraction at material interfaces and in the Earth's atmosphere Reflection, refraction, and diffraction analysis in microwave link design for a specified terrain profile Empirical path loss models for point-to-point ground links Statistical fading models Standard techniques for prediction of ground wave propagation Ionospheric propagation, with emphasis on the skywave mechanism at MF and HF and on ionospheric perturbations for Earth-space links at VHF and higher frequencies A survey of other propagation mechanisms, including tropospheric scatter, meteor scatter, and propagation effects on GPS systems Radiowave Propagation incorporates fundamental materials to help senior undergraduate and graduate engineering students review and strengthen electromagnetic physics skills as well as the most current empirical methods recommended by the International Telecommunication Union. This book can also serve as a valuable teaching and reference text for engineers working with wireless communication, radar, or remote sensing systems.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: El objetivo de este proyecto ha sido el desarrollo de una aplicación en MATLAB que permite obtener medidas de potencia de señal georreferenciadas. Estas medidas, debidamente procesadas, permiten estudiar la propagación radio en el entorno en un sistema de telecomunicaciones, y determinar cómo afectará la atenuación a la señal. Para el procesado de datos se ha utilizado la aplicación Campaign para MATLAB, facilitada por el director del presente TFG. El proyecto está estructurado de la siguiente manera: Explicación de la propagación radio y su estudio mediante los modelos de propagación, para lograr caracterizar la atenuación que sufren las ondas electromagnéticas en un medio concreto. Introducción a las campañas de medidas y explicación del criterio de Lee, esencial para llevar a cabo un estudio correcto. En esta parte también se explica el concepto de ajuste de los modelos para adaptarlos a entornos concretos, además de la generación de modelos nuevos, que es lo que se realizará mediante los datos obtenidos por la aplicación que se ha desarrollado para demostrar su funcionamiento. Desarrollo de la aplicación para realizar las medidas. Este es el capítulo más extenso, ya que comprende la mayor parte del trabajo realizado. Además de los principios teóricos en los que se ha basado la herramienta, narra desde las primeras pruebas hasta la obtención de una aplicación final completamente funcional, detallando el código y el funcionamiento de aquellas funciones más relevantes. El código de la aplicación final se encuentra en el anexo debido a su extensión. Resumen de la aplicación Campaign y de las características más relevantes para el proyecto. También se explican las modificaciones que se han realizado para interpretar los datos extraídos por la herramienta desarrollada. Presentación de los resultados obtenidos después de procesar con Campaign las medidas realizadas, y se muestra la generación de un nuevo modelo de propagación para cada frecuencia. Conclusión del proyecto.

Available in PDF, EPUB and Kindle. Book excerpt: En la presente investigación se da una explicación de los aspectos generales referentes a la Teoría de la Propagación de Radio Frecuencia, incluyendo los modelos de predicción de pérdidas. Para tal efecto, se parte de lo general a lo particular. El primer objetivo de este proyecto es el estudio de la propagación de RF desde los mecanismos básicos de propagación, hasta las características correspondientes a las bandas de frecuencia estudiadas, y un estudio completo sobre los modelos de propagación más importantes que sirven para caracterizar el canal de comunicación. La primera parte consiste en una investigación sobre los tipos de ondas y sus características vistos en el capítulo 1, los mecanismos básicos que intervienen en la propagación a través de la atmósfera terrestre explicados en el capítulo 2; posteriormente se presenta un estudio de las propiedades de las diferentes capas de la atmósfera y de cómo se comportan estas con las ondas de Radio Frecuencia vistas en el capítulo 3, así como también de las diferentes ondas que se pueden clasificar, sus principales características de propagación; esto con el objetivo de que la información sirva de preámbulo para poder entender con mayor facilidad lo que pasa cuando se propagan ondas por el especio terrestre. Después de entender la propagación de las ondas en el espacio terrestre, se hace una descripción y se ahonda en el tema de Propagación de la Radio Frecuencia correspondiente a cada una de las bandas de frecuencias que se explican a detalle en el capítulo 4. A partir de este punto se hace un análisis completo sobre los modelos más importantes de predicción de pérdidas por trayectoria presentados en el capítulo 5 y que son de gran utilidad para analizar el canal de comunicación. El objetivo final, es la presentación de un software didáctico que simule las perdidas por trayectoria en base a cuatro modelos de propagación analizados en este proyecto los cuales son: Modelo del Espacio Libre o modelo de Friis, Modelo de.

Download or read book Analysis and Modeling of Radio Wave Propagation written by Christopher John Coleman and published by Cambridge University Press. This book was released on 2017-01-05 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive guide helps readers understand the theory and techniques needed to analyze and model radio wave propagation in complex environments. All of the essential topics are covered, from the fundamental concepts of radio systems, to complex propagation phenomena. These topics include diffraction, ray tracing, scattering, atmospheric ducting, ionospheric ducting, scintillation, and propagation through both urban and non-urban environments. Emphasis is placed on practical procedures, with detailed discussion of numerical and mathematical methods providing readers with the necessary skills to build their own propagation models and develop their own techniques. MATLAB functions illustrating key modeling ideas are provided online. This is an invaluable resource for anyone wanting to use propagation models to understand the performance of radio systems for navigation, radar, communications, or broadcasting.

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.
