DIGITAL MODEM TECHNIQUES FOR LOW COST DOMESTIC SCPC EARTH STATIONS

摘要

This paper presents a number of new ideas which have been implemented in the design of low cost SCPC earth stations. Emphasis is placed on achieving low cost solutions and voice data for transmission problems that are encountered by business users. Our original modulation technique and the subsystems are described. The tradeoffs between low-cost and high-performance are outlined for the main subsystems.
