Este artigo propõe comunicação bidirecional sobrecarregada de múltiplas entradas e saídas (MIMO) com codificação de rede de camada física (PLNC) para aumentar a velocidade de transmissão em redes multihop sem fio heterogêneas, onde o número de antenas no relé é menor que o dos terminais. O sistema de comunicação MIMO sobrecarregado proposto aplica pré-codificação e filtragem de relés para reduzir a complexidade computacional, apesar da velocidade de transmissão. Um filtro baseado em autovetores é proposto para o filtro de relé. Além disso, propomos uma técnica para selecionar o melhor filtro entre filtros candidatos baseados em autovetores. O desempenho da comunicação bidirecional MIMO sobrecarregada proposta é avaliado por simulação computacional em uma rede heterogênea sem fio de 2 saltos. A técnica de seleção de filtro proposta atinge um ganho de cerca de 1.5dB no BER de 10-5 em uma rede de 2 saltos onde 2 antenas e 4 antenas são colocadas no relé e no terminal, respectivamente. Este artigo mostra que a multiplexação espacial de 6 fluxos é possível no sistema com 2 antenas no relé.

Abstract: This paper proposes overloaded multiple input multiple output (MIMO) bi-directional communication with physical layer network coding (PLNC) to enhance the transmission speed in heterogeneous wireless multihop networks where the number of antennas on the relay is less than that on the terminals. The proposed overloaded MIMO communication system applies precoding and relay filtering to reduce computational complexity in spite of the transmission speed. An eigenvector-based filter is proposed for the relay filter. Furthermore, we propose a technique to select the best filter among candidates eigenvector-based filters. The performance of the proposed overloaded MIMO bi-directional communication is evaluated by computer simulation in a heterogeneous wireless 2-hop network. The proposed filter selection technique attains a gain of about 1.5dB at the BER of 10-5 in a 2-hop network where 2 antennas and 4 antennas are placed on the relay and the terminal, respectively. This paper shows that 6 stream spatial multiplexing is made possible in the system with 2 antennas on the relay.
