A hybrid model for broadband multiple-input multiple-output (MIMO) relay-aided indoor power line communications (PLC) system was proposed in this paper.The proposed model combines the top-down and bottom-up approaches and extends to a two-hop relay-aided cooperative system with variable gain relay in amplifyand-forward (AF) mode.Based on the proposed PLC model and generated channel,the channel statistical characteristics are further investigated in 2 MHz ~ 100 MHz bandwidth.Simulated results show that the proposed model overcomes the difficulties that the existing models need a lot of topological information of the network or measurements information.It provides a practical simulation analysis method for cooperative relay MIMO-PLC system.The results also show that cooperative MIMO relaying communications can improve the indoor PLC performances and communication reliability.
