Download Parabolic Equation Methods for Electromagnetic Wave Propagation Book in PDF, ePub and Kindle
Provides scientists and engineers with a tool for accurate assessment of diffraction and ducting on radio and radar systems. The author gives the mathematical background to parabolic equations modeling and describes simple parabolic equation algorithms before progressing to more advanced topics such as domain truncation, the treatment of impedance boundaries, and the implementation of very fast hybrid methods combining ray-tracing and parabolic equation techniques. The last three chapters are devoted to scattering problems, with application to propagation in urban environments and to radar-cross- section computation.

Download Radio Propagation Measurement and Channel Modelling Book in PDF, ePub and Kindle
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.

Download Radiowave Propagation Book in PDF, ePub and Kindle
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.

Download Radio Wave Propagation in the Marine Boundary Layer Book in PDF, ePub and Kindle
Based on his many years of professional experience at leading companies in communications technology, the author describes an analytical solution for wave propagation over the sea surface in an atmospheric boundary layer. His approach allows the detailed analysis of combined effects of diffraction, refraction and scattering in random media. While specific applications covered are targeted at radio wave propagation over the sea surface, a similar approach is applicable to many problems in underwater acoustics, seismology, solid matter physics and astrophysics.

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.

Download Advanced Parabolic Equation-Based Propagation Modeling for Train Communication Systems Book in PDF, ePub and Kindle
With the continuing expansion of metropolitan areas, the demand for efficient mass transportation systems is increasing accordingly. An emerging wireless technology for rail signaling, which can significantly improve the efficiency of light rail, subway, and high-speed train transit systems, is communication-based train control (CBTC). In CBTC systems, trains communicate wirelessly with wayside access points, which are connected to a central control station. A prerequisite for the deployment of such systems is the existence of a suitable propagation model, which can provide accurate path-loss predictions of corresponding wireless channels. This is of particular importance due to the safety-critical nature of rail signaling and the rapid, cost-effective nature of system deployment. This thesis presents an advanced propagation modeling tool, based on parabolic equation methods, to characterize radio wave propagation in realistic, complex railway environments. Concrete guidelines are provided on how to extract input models from point cloud data and what level of detail is necessary and sufficient to obtain results agreeing with measured data. Moreover, enhanced techniques dealing with geometrical variations of guideways and practical antenna patterns are presented. The accuracy and efficiency of the developed propagation model are demonstrated in various practical scenarios. Furthermore, a robust approach on extracting surrogate models from arbitrary tunnel geometries is proposed. The extracted surrogate models can lead to significant computational savings, especially in optimization studies where repetitive calls of the propagation model are required. The thesis also presents two hybrid propagation modeling techniques, aimed at achieving a better trade-off between accuracy, efficiency, and generality, via using the advantages of one method to compensate for the limitations of another and vice versa. Moreover, effects of uncertainty in the environment and experimental setup on the variability of predicted signal strength are investigated. A new approach that can incorporate wall roughness into the model is introduced. It can be applied to tunnels with arbitrary cross-section geometries and large-scale surface roughness. Finally, a physics-based optimization strategy is presented to optimize the placement of access points for train communication systems. The validity and usefulness of the proposed methodology are demonstrated in an actual deployment site of CBTC systems.
