Neste artigo, propomos um esquema de relé filter-and-forward com coleta de energia para transmissão de portadora única em canais seletivos de frequência. O nó de retransmissão coleta energia do sinal de transmissão do nó de origem e de seu próprio sinal de transmissão por reciclagem de energia própria. O sinal recebido pelo nó relé é filtrado para suprimir a interferência entre símbolos e então encaminhado ao nó de destino usando a energia coletada. Consideramos um método de projeto de filtro baseado na maximização da relação de potência sinal-interferência mais ruído, sujeito a uma restrição que limita a potência de transmissão do relé. Além disso, fornecemos um algoritmo baseado em pesquisa da seção áurea para otimizar a taxa de divisão de energia do protocolo de divisão de energia. Os resultados da simulação mostram que a filtragem e a auto-reciclagem de energia do esquema proposto são eficazes na melhoria do desempenho. Também é mostrado que o esquema proposto é útil mesmo quando apenas informações parciais do estado do canal estão disponíveis.

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.
