Dans cet article, nous proposons un schéma de relais de filtrage et de transfert avec récupération d'énergie pour la transmission sur une seule porteuse dans des canaux sélectifs en fréquence. Le nœud relais récupère l'énergie à la fois du signal de transmission du nœud source et de son propre signal de transmission par recyclage d'auto-énergie. Le signal reçu par le nœud relais est filtré pour supprimer les interférences entre symboles, puis transmis au nœud de destination en utilisant l'énergie récupérée. Nous considérons une méthode de conception de filtre basée sur la maximisation du rapport de puissance signal/interférence plus bruit, soumise à une contrainte qui limite la puissance d'émission du relais. De plus, nous fournissons un algorithme basé sur la recherche de la section dorée pour optimiser le rapport de répartition de puissance du protocole de répartition de puissance. Les résultats de la simulation montrent que le filtrage et le recyclage auto-énergétique du schéma proposé sont efficaces pour améliorer les performances. Il est également démontré que le schéma proposé est utile même lorsque seules des informations partielles sur l'état du canal sont disponibles.

Abstract: In this paper, we propose a filter-and-forward relay scheme with energy harvesting for single-carrier transmission in frequency-selective channels. The relay node harvests energy from both the source node transmit signal and its own transmit signal by self-energy recycling. The signal received by the relay node is filtered to suppress the inter-symbol interference and then forwarded to the destination node using the harvested energy. We consider a filter design method based on the signal-to-interference-plus-noise power ratio maximization, subject to a constraint that limits the relay transmit power. In addition, we provide a golden-section search based algorithm to optimize the power splitting ratio of the power splitting protocol. The simulation results show that filtering and self-energy recycling of the proposed scheme are effective in improving performance. It is also shown that the proposed scheme is useful even when only partial channel state information is available.
