Spread spectrum systems: a point of view between technology and management.

Abstract

Only recently has technology come to the point of making circuitry and systems reasonably small, reliable, and inexpensive so as to enable practical implementations of spread spectrum (SS) concepts. Viewed as a motivating force encouraging the growth of the field, this recently developed capability for practical SS systems must be reinforced by the additional pressure of more and greater demands being made on communications systems than ever before. Increased message traffic from a higher number of users is creating a need for protection of information from interference and eavesdropping. As a result of these two major forces, the availability of systems and components coupled with the need for improved communications, the field of SS communications has rapidly emerged in recent years as a major thrust in the technical community. This thesis provides a summary of the principles upon which SS systems have developed and the progress of frequency management involving spread spectrum systems.
