A Perspective on Multiaccess Channels

Abstract

The Information Theoretic Approach and the Collision Resolution Approach to Multiaccess Channels are reviewed in terms of the Underlying Communication Problems that both are modelling. We give some perspective on the strengths and weakness of these approaches and argue for the need of a more combined approach focused on coding and decoding techniques. For the last ten years there have been at least three bodies of research on multiaccess channels, each proceeding in virtual isolation from the others and each using totally different models. The objective here is to contrast these bodies of work and to give some perspective on what is needed to provide some unification between the areas. We shall refer to the three areas as collision resolution, multiaccess information theory, and spread spectrum.
