Study of Temporally Coupled Framed Access Scheme in Slotted ALOHA

Abstract

This paper presents a further study of the access scheme in framed slotted ALOHA. A random-access (RA) scheme is presented in the erasure channel where the collision happens and deploy the iterative decoding to cancel the interference. The contribution is to transmit the packets in a temporally coupled manner by limiting the constraint of the length of the time frame. The final result shows that the investigated access scheme can proceed well. The feasible number of user collision per slot and the number of frames in a superframe is described to obtain the achievable throughput with few packet loss rate of the scheme.
