A Scheme for Multiuser Communications based on Energy Division

We discuss a multiple-access protocol that discriminates different users on the basis of their energy. Users are assumed to share the same bandwidth, the same pulse and are decoded according to their received magnitudes. This proposal promises to achieve larger efficiency when jointly applied with classical protocols especially in scenarios where the same low-cost terminals are deployed in large numbers as in sensor networks and in personal-area networks. Analytical results, confirmed by numerical simulations, are derived for performance evaluation on additive white Gaussian noise channels.
