Book Description
With its higher power and superior video and audio quality, Direct Broadcast Satellite (DBS) communications is proliferating worldwide. Many new DBS systems are evolving and with the introduction of HDTV, DBS technology is predicted to become even more prevalent. Written by a leading DBS authority, this book is required reading for anyone involved in this burgeoning field. This comprehensive reference describes the history and structure of DBS systems, the regulatory environment, the subsystems that support it, and the underlying compression technology that makes it commercially feasible. Direct Broadcast Satellite Communications can be read as a broad overview of DBS systems or can serve as a detailed technical description. In particular, the author thoroughly explains how MPEG compression standards are used to implement modern satellite broadcast systems. You will find complete information on key topics such as: International and FCC regulations Radio frequency components of DBS systems, including the shaped reflector antenna Forward error correction, looking at block codes, interleaving, and Viterbi decoding The use of cryptography for conditional access to subscription services MPEG system and transport layer MPEG-2 video and audio compression Connecting terrestrial systems and DBS uplinks The Integrated Receiver Decoder In addition, the book explores future developments, including the Spaceway and the Global Broadcast Service, as well as the MPEG-4 compression standards. Numerous case studies involving DIRECTV(TM) and the European DVB standard appear throughout the book. For other books in this series, see http://www.awl.com/cseng/wirelessseries/

Book Description
Extensive revision of the best-selling text on satellite communications — includes new chapters on cubesats, NGSO satellite systems, and Internet access by satellite There have been many changes in the thirty three years since the first edition of Satellite Communications was published. There has been a complete transition from analog to digital communication systems, withanalog techniques replaced by digital modulation and digital signal processing. While distribution of television programming remains the largest sector of commercial satellite communications, low earth orbit constellations of satellites for Internet access are set to challenge that dominance. In the third edition, chapters one through three cover topics that are specific to satellites, including orbits, launchers, and spacecraft. Chapters four through seven cover 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. Chapters eight through twelve cover applications that include non-geostationary satellite systems, low throughput systems, direct broadcast satellite television, Internet access by satellite, and global navigation satellite systems. The chapter on Internet access by satellite is new to the third edition, and each of the chapters has been extensively revised to include the many changes in the field since the publication of the second edition in 2003. Two appendices have been added that cover digital transmission of analog signals, and antennas. An invaluable resource for students and professionals alike, this book: Focuses on the fundamental theory of satellite communications Explains the underlying principles and essential mathematics required to understand the physics and engineering of satellite communications Discusses the expansion of satellite communication systems in areas such as direct-broadcast satellite TV, GPS, and internet access Introduces the rapidly advancing field of small satellites, referred to as SmallSats or CubeSats Provides relevant practice problems based on real-world satellite systems Satellite Communications is required reading for undergraduate and postgraduate students in satellite communications courses and an authoritative reference for engineers working in communications, systems and networks, and satellite operations and management.

Book Description
Designed as a text for the undergraduate students of Electronics and Communication Engineering/Electronics and Telecommunication Engineering as well as for postgraduate students of Communication Systems/Electronics and Communication Engineering, the book presents all the topics related to satellite communication in an organised way, starting from the basic concepts to the latest advancements in the field. The book commences with an introductory chapter that familiarises the readers with the evolution of satellite communication. The following chapters expatiate on orbital mechanics, perturbation factors of the orbit and different orbit configurations. Next, the launching mechanism and satellite sub-systems, which together configure a complete satellite system, are focused. The book further explicates the link calculation to facilitate the design aspect. In addition, satellite access mechanism, and Internet linking via satellite are also outlined in the text. Finally, the concluding chapters of the book elaborate navigation satellite, direct broadcasting satellite television, VSAT and special purpose satellites. With all the contents enriched by the vast experience of the author, the book provides a comprehensive treatment of the subject, and enables the students to rely upon this exclusive book only.
