Space and terrestrial systems in the digital network evolution
Abstract
An account is given of the development history and state-of-the-art in digital communications systems in use or planned by advanced countries, encompassing satellite networks, cellular mobile radio-based networks, and fiber-optic terrestrial systems. The general trend in communications technologies is noted to have for some time been toward the digital representation of signals and their TDMA processing for transmission. Attention is given to the prospects for satellite communications at frequencies above 10 GHz, the expansion of cellular radio networks, and the impact that optical digital data processing may have on fiber-optic communications.
