Abstract

In this paper we present SPIRAP, SPinal Random Access Protocol, a new method for multiuser detection over wireless fading channel. SPIRAP combines sequential decoding with rateless Spinal code. SPIRAP appears to be an efficient protocol for transmitting small packets in a minimally controlled network and can be attractive for the Internet of Things (IOT) applications. The algorithm applies equivalently to any other rateless code, we chose Spinal for its good performance. We show that SPIRAP may achieve higher rate than TDMA and ALOHA in some cases and without the need for users synchronization.
