Download Modeling of Land Mobile Satellite Radio Propagation Channel Book in PDF, ePub and Kindle
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.

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 Radio Wave Propagation and Channel Modeling for Earth-Space Systems Book in PDF, ePub and Kindle
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 Mobile Fading Channels Book in PDF, ePub and Kindle
Mobile channel fading is a loss in transmission intensity caused by changes in the transmission medium. By dealing with the modelling, analysis and simulation of mobile fading channels this text provides a fundamental understanding of many issues in the area of mobile fading channel modelling.; The main topics addressed in the volume are: fundamentals of stochastic and deterministic channel models and modelling and simulation of frequency-nonselective and frequency-selective fading channels. The guide also features methods for the design and realization of efficient channel simulators and fast channel simulators and MATLAB-programs for the evaluation and simulation of mobile fading channels.
