Avanços recentes na comunicação cooperativa e na codificação de redes sem fio (NC) podem levar a enormes ganhos de desempenho em sistemas de retransmissão. Neste contexto, focamos no cenário de retransmissão bidirecional, onde dois nós trocam informações através de uma retransmissão comum. Projetamos um esquema NC prático baseado em codificação de superposição (SC) para retransmissão half-duplex de decodificação e encaminhamento (DF), onde o objetivo é aumentar a taxa alcançável. Aproveitando o link direto e fornecendo uma divisão de potência abaixo do ideal, porém eficiente, entre as camadas sobrepostas, nosso esquema de retransmissão bidirecional SC proposto supera os esquemas de referência, incluindo o conhecido esquema DF-NC de 3 etapas e a capacidade de Esquemas de 2 etapas para um grande conjunto de SNRs, aproximando-se ao mesmo tempo do limite de desempenho.

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.

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.
