In this paper we investigate the use of Power-Line Communication (PLC) to assist cooperative wireless relaying. We consider a communication scheme that uses the power-line to initialize and synchronize wireless amplify-and-forward (AF) relays and to broadcast information between the relays. Starting from an analysis of transfer functions and noise measurements of PLC channels in office and residential environments we propose a power-line transmission scheme for the inter-relay-communication and assess the influence of this scheme on wireless relaying. This scheme is based on linear pre-coded OFDM; it is designed to optimally exploit the frequency diversity available on PLC channels. The use of PLC leads to a very flexible way of enhancing wireless communications by plugging in additional relays where they are needed – without additional wiring.
