Dalam makalah ini, kami menyiasat masalah penjadualan adil berkadar (PFS) untuk sistem OFDM berbilang pengguna, dengan mengambil kira kesan panjang paket. Panjang paket mempengaruhi skema penjadualan dengan cara setiap paket yang dijadualkan harus dipastikan dihantar sepenuhnya dalam bingkai yang dijadualkan. Kami merumuskan masalah PFS sebagai masalah pengoptimuman. Berdasarkan pemerhatian terhadap struktur penyelesaian optimum, kami mencadangkan algoritma penjadualan heuristik yang terdiri daripada dua peringkat. Pertama, subcarrier diperuntukkan di kalangan pengguna tanpa mengambil kira kekangan panjang paket. Kemudian pada peringkat kedua, pelarasan semula subcarrier dilakukan dengan cara yang lebihan subcarrier daripada pengguna yang berpuas hati dengan panjang dilepaskan dan diperuntukkan di kalangan pengguna yang tidak berpuas hati dengan panjang. Objektifnya adalah untuk menyediakan keadilan berkadar di kalangan pengguna sambil menjamin penghantaran lengkap setiap paket yang dijadualkan. Keputusan simulasi menunjukkan bahawa skim yang dicadangkan mempunyai prestasi yang agak hampir dengan skim optimum dari segi Multi-carrier Proportional Fairness Measure (MCPFM), throughput dan purata kelewatan paket.

Abstract: In this paper, we investigate the proportional fair scheduling (PFS) problem for multiuser OFDM systems, considering the impact of packet length. Packet length influences scheduling schemes in a way that each scheduled packet should be ensured to be completely transmitted within the scheduled frames. We formulate the PFS problem as an optimization problem. Based on the observations on the structure of optimal solutions, we propose a heuristic scheduling algorithm that consists of two stages. First, subcarriers are allocated among users without considering the packet length constraint. Then on the second stage, subcarrier readjustment is done in a way that surplus subcarriers from length-satisfied users are released and allocated among length-unsatisfied users. The objective is to provide proportional fairness among users while guaranteeing complete transmission of each scheduled packet. Simulation results show that the proposed scheme has quite close performance to the optimal scheme in terms of Multi-carrier Proportional Fairness Measure (MCPFM), throughput and average packet delay.
