Wireless Communications Design Handbook Terres- Trial Mobile Interference

Reinaldo Perez9780125507219, 0-12-550721-6

Volume One of the Wireless Communications Design Handbook provides an in-depth look at interference problems in satellite communications. The material presented is from a satellite or spacecraft hardware point of view rather than from theoretical models. Each satellite subsystem is described in detail to point out interference and noise problems associated with it. The book also addresses typical architectures and hardware design issues in satellites. In addition, a detailed look at space interference is discussed with emphasis on the possible impact on satellite electronics. Key Features * An applications-oriented reference for engineers, system designers, and practitioners * Addresses the most common interference concerns in ground mobile wireless communications systems * Hardware-oriented approach to interference and noise concerns as well as satellite subsystem design * All satellite subsystems described in great technical detail * Significantly covers space interference with a slanted approach to satellite hardware effects * Covers modern hardware design for low earth orbit satellites to be used in wireless communications
