Application of multiuser coding to random access protocols
G. Thomas · IEEE Transactions on Communications · 1988
The usefulness of multiuser coding for throughput enhancement in various random-access protocols with (0, 1, e) feedback is examined. A scheme is proposed in which the user population is divided into two or more classes and multiuser coding is used in such a manner that all collisions among at most one-user-per-class are resolved by virtue of the multiuser code. For ALOHA, tree, and interval-splitting random-access protocols, significant improvements in throughput are demonstrated when multiuser coding techniques are used.>
