Recent Advances in Coding for Multiple Access Communication Systems

Abstract

During the past few years it has been demonstrated that coding can play a major role in multiple-access communication systems. In addition to providing errorcontrol capability as in a single-user system, coding can actually provide the multipleaccess capability in a multi-user system. In this paper we concentrate on one such system, the spread-spectrum multiple-access system in which the communication capacity of the channel is shared by several asynchronous radio frequency signals that occupy the same bandwidth. Recent results on the analysis of these systems and on the selection of codes for multiple-access applications are presented.
