Description
Wiley Satellite Communications An Indian Adaptation 3rd Edition 2021 by Timothy Pratt and Jeremy Allnutt
Satellite Communications is a comprehensive textbook designed for undergraduate and postgraduate courses on satellite communications. The book focuses on the underlying principles and essential mathematics required to understand the physics and engineering of satellite communications. Beginning with the topics that are specific to satellites, including orbits, launchers, and spacecraft, the book goes on to explain the principles of digital communication systems, radio frequency communications, digital modulation and multiple access techniques, and propagation in the earth's atmosphere, topics that are common to all radio communication systems. About the AuthorTimothy Pratt is an Emeritus Professor of the Bradley Department of Electrical and Computer Engineering at Virginia Tech, having retired in 2013. Dr. Pratt is a lifetime senior member of the IEEE. Jeremy Allnutt is an Emeritus Professor of the Electrical and Computer Engineering Department of George Mason University, having retired in 2014. His primary interest is radiowave propagation effects on satellite links, which he pursued at research establishments in England and Canada, before working at Intelsat in the USA from 1979 to 1994.
