Les progrès récents en matière de communication coopérative et de codage de réseau (NC) sans fil pourraient conduire à d'énormes gains de performances dans les systèmes de relais. Dans ce contexte, nous nous concentrons sur le scénario du relais bidirectionnel, dans lequel deux nœuds échangent des informations via un relais commun. Nous concevons un schéma NC pratique basé sur le codage par superposition (SC) pour le relais semi-duplex Decode-and-Forward (DF), dont l'objectif est d'augmenter le débit réalisable. En tirant parti de la liaison directe et en fournissant une division de puissance sous-optimale mais efficace entre les couches superposées, notre schéma de relais bidirectionnel SC proposé surpasse les schémas de référence, y compris le schéma DF-NC en 3 étapes bien connu et la capacité de Schémas en 2 étapes pour un large ensemble de SNR, tout en se rapprochant de près de la limite de performance.

Abstract: Recent advances in cooperative communication and wireless Network Coding (NC) may lead to huge performance gains in relay systems. In this context, we focus on the two-way relay scenario, where two nodes exchange information via a common relay. We design a practical Superposition Coding (SC) based NC scheme for Decode-and-Forward (DF) half-duplex relaying, where the goal is to increase the achievable rate. By taking advantage of the direct link and by providing a suboptimal yet efficient power division among the superposed layers, our proposed SC two-way relaying scheme outperforms the reference schemes, including the well-known 3-step DF-NC scheme and the capacity of 2-step schemes for a large set of SNRs, while approaching closely the performance bound.
