DISTRIBUTED SATELLITE CIRCUMGLOBAL COMMUNICATION TECHNIQUE STUDY, VOLUME I.
Abstract
The purpose of this investigation is to provide an initial evaluation of techniques applicable to a global communications network utilizing orbiting dipoles as a scattering medium. Emphasis has been placed on those techniques which are peculiar to the propagation medium employed. Consideration of the scattering mechanism led to development of a quaternary modulation technique. An analysis has been made of the performance of various error correcting and error detecting codes which can be used in conjunction with a one of five modulation system. The doppler spread was calculated very accurately as a function of the orbital parameters and station geometry. Transmission calculations were made and performance of the system compared to that of a discrete passive satellite system. (Author)
