Rateless multiple access over noisy channel

Published: 28 June 2010 Publication History

Abstract

Multiple access technology is a key issue to efficiently share the available scarce sources among a large number of users. We present a novel multiple access scheme denominated as rateless multiple access (RMA) scheme, in which users do not coordinate their transmissions but implement a random multiple access scheme as simply as time-slotted ALOHA system does. Each user utilizes Rateless codes with its own seed to protect its message, conquer the problem of collisions to packets and distinguish from each other. In this paper, we investigate the scenario where the transmission is over the noisy channel and present the schemes of both the transmitters and the receiver. Simulation results finally demonstrate the efficiency of the proposed RMA scheme.
