Manual of satellite communications

The design and operation of satellite communications systems (SCSs) are examined in an introductory text for graduate engineering students. The history of SCSs during the period 1962-1982 is traced with an emphasis on US commercial ventures, and the overall function and economics of SCSs is reviewed. Individual chapters are devoted to orbits, launch sequences, and on-station positioning; spacecraft systems; communications payloads; earth stations and terrestrial links; uplinks and downlinks; linear systems and signals; random processes and noise; analog modulation; digital communicatins; coding and forward error detection; transmission impairments; and networks and systems (multiplexing, FDMA, TDMA, CDMA, and variable-access demand asignment. Graphs showing the apparent motion of the sun with respect to an earth satellite; summaries of Fourier analysis, Hilbert transforms, vector and matrix representations; and a table listing the characteristics of major SCSs are included in appendices.
