Описание: This is the first book primarily about the satellite payload of satellite communications systems. It represents a unique combination of practical systems engineering and communications theory. It tells about the satellites in geostationary and low-earth orbits today, both the so-called bent-pipe payloads and the processing payloads.
Описание: Significant progress has been made in the last decade in the understanding and modeling of propagation effects on radio wave propagation in the bands utilized for satellite communications, including extensive direct measurements and evaluation utilizing orbiting satellites. This book provides a single source for a comprehensive description and analysis of all of the atmospheric effects of concern for todays satellite systems and the tools necessary to design the links and evaluate system performance. Many of the tools and calculations are provided in a handbook form, with step-by-step procedures and all necessary algorithms in one place to allow direct calculations from one source. Covers: Satellite Orbits, Satellite Subsystems, The RF Link, Link System Performance, Transmission Impairments, Propagation Effects Modeling Analog Satellite Systems, Signal Processing Digital Satellite Systems, Satellite Multiple Access, Mobile Satellite Networks, Satellite Broadband, Satellite Applications and Trends
