It has been demonstrated that coding can play a major role in multiple-access satellite communication systems. In addition to providing error-control capability as in single-user communication systems, coding actually provides the multiple-access capability in many multi-user systems. The subject of this report is the use of coding techniques in a multiple-access satellite communication system in which the communication capacity is to be shared by several asynchronous radio-frequency signals that occupy the same bandwidth. However, most of the concepts and techniques discussed in the paper apply to a wide variety of multiple-access communication systems in addition to satellite systems. results applicable to multiple-access communication systems from the fields of information theory, algebraic coding theory, and communication theory are presented along with a discussion of important mathematical models of multiple-access satellite systems and practical considerations and constraints in the design of such systems. Analytical results on the performance of phase-coded spread-spectrum multiple-access systems are obtained and some new multiple-access communication schemes for a satellite link in a computer-communication network are discussed.
