Abstract:
In this paper, we study via simulation the performance of irregular repetition slotted ALOHA under multi-packet detection and different patterns of the load process. On the one hand, we model the arrival process with a version of the M/G/∞ process able to exhibit a correlation structure decaying slowly in time. Given the independence among frames in frame-synchronous coded-slotted ALOHA (CSA), this variation should only take effect on frame-asynchronous CSA. On the other hand, we vary the marginal distribution of the arrival process using discrete versions of the Lognormal and Pareto distributions, with the objective of investigating the influence of the right tail. In this case, both techniques should be affected by the change, albeit to a different degree. Our results confirm these hypotheses and show that these factors must be taken into account when designing and analyzing these systems. In frameless operations, both the shape of the packet arrivals tail distribution and the existence of short-range and long-range correlations strongly impact the packet loss ratio and the average delay. Nevertheless, these effects emerge only weakly in the case of frame-aligned operations, because this enforces the system to introduce a delay in the newly arrived packets (until the beginning of the next frame), and implies that the backlog of accumulated packets is the key quantity for calculating the performance.

Abstract:
ABSTRAKPenggunaan Non-Orthogonal Multiple Access (NOMA) pada sistem komunikasi dapat memberi kebebasan bagi user untuk mengirimkan informasi secara bersamaan tanpa harus memperebutkan timeslot ataupun frekuensi. Coded Random Access (CRA) adalah salah satu bagian dari Coded Comain-NOMA (CDNOMA) yang menggunakan kode tanpa ortogonal untuk komunikasi uplink. Terinspirasi dari Additive Links On Line Hawaii Area (ALOHA), kami menggunakan metode Irregular Repetition Slotted ALOHA (IRSA) dengan tiga jumlah slot node dan sembilan degree distribution pada model kanal Line Of Sight (LOS) dan Non-LOS (NLOS). Kami menggunakan metrik pengukuran berupa throughput dan Packet Loss Ratio (PLR) untuk memperoleh hasil simulasi. Dari simulasi yang ekstensif, kami membuktikan bahwa IRSA stabil pada jumlah slot node yaitu 75, 150 dan 300 yang memperoleh throughput di sekitar 0.75 paket/slot.Kata kunci: Coded Random Access, Non-Orthogonal Multiple Access, Slotted ALOHA, Successive Interference Cancellation ABSTRACTThe use of Non-Orthogonal Multiple Access (NOMA) in communication systems can provide users the freedom to transmit information simultaneously without having to fight over timeslots or frequencies. Coded Random Access (CRA) is a part of Coded Domain-NOMA (CD-NOMA) that uses orthogonal code for uplink communication. Inspired by the Additive Links On Line Hawaii Area (ALOHA), we use the Irregular Repetition Slotted ALOHA (IRSA) method with three number of node slots and nine degree distributions on the Line Of Sight (LOS) and Non-LOS (NLOS) channel models. We use measurements in the form of throughput and Packet Loss Ratio (PLR) to obtain simulation results. From extensive simulations, we prove that IRSA is stable on a wide number of node slots of 75, 150 and 300 that acquire throughput in about 0.75 packets/slot.Keywords: Coded Random Access, Non-Orthogonal Multiple Access, Slotted ALOHA, Successive Interference Cancellation

Abstract:
One of the main requirements for next generation mobile or wireless communication systems is to effectively support a large number of machine type communication devices for Internet of things applications. In order to improve the random access capability in frame-based slotted Aloha environments, coded random access techniques have been proposed, in which multiple copies of a packet are transmitted per frame and the copies are cancelled out from the received signal if any single copy is successfully received. They, however, may increase the transmission power by sending multiple copies per frame. Above all, for systems with a small number of slots per frame, they may not be able to improve the performance by readily reaching a congested state. This paper proposes a new frame-based random access scheme, which sends at most one copy of a packet per frame but uses interference cancellation to improve the performance. If a successfully received packet is a retransmitted one, the previously transmitted signals for the packet can be cancelled out from the received signals for trying to decode other received packets. The proposed scheme has different characteristics than coded random access schemes and can be also combined with them to further improve the performance.
