Cet article considère le problème d'allocation de sous-porteuse proportionnellement équitable (PF) dans un système de diffusion à accès multiple par répartition orthogonale de la fréquence (OFDMA) multi-sauts avec relais de décodage et de retransmission (DF). Le problème est formulé comme un problème de programmation d'entiers binaires mixtes dans le but d'obtenir une équité proportionnelle entre les utilisateurs et d'exploiter la diversité fournie par l'évanouissement sélectif en fréquence indépendant entre les sauts. Puisqu’il est prohibitif de trouver la solution optimale, deux schémas heuristiques efficaces sont proposés. Les résultats de la simulation indiquent qu'avec les mêmes performances d'équité, les schémas proposés permettent d'obtenir un gain de capacité considérable par rapport à la méthode conventionnelle de planification PF.

Abstract: This paper considers the proportional fair (PF) based subcarrier allocation problem in a multihop orthogonal frequency division multiple access (OFDMA) broadcast system with decode-and-forward (DF) relays. The problem is formulated as a mixed binary integer programming problem with the objective to achieve proportional fairness among users and exploit the diversity provided by the independent frequency selective fading among hops. Since it is prohibitive to find the optimal solution, two efficient heuristic schemes are proposed. Simulation results indicate that with the same fairness performance, the proposed schemes achieve considerable capacity gain over the conventional PF scheduling method.
