Tabu-search procedure for PAPR reduction in PLC channels

In this paper a Tabu Search based procedure for Peak to Average Power Ratio (PAPR) reduction in Power Line Communication (PLC) channels is presented. The Orthogonal Frequency Division Multiplexing has been assumed as communication technique. The Selected Mapping approach is applied in order to investigate the possibility to define with a limited computational cost a phase factors vector that represents a sub-optimal solution. The study has been developed referring to the real case of a PLC system implemented in a mega yacht.
