One of the major drawback of orthogonal frequency-division multiplexing (OFDM) systems is the large Peak-to-Average power Ratio (PAR) of the transmit signal. High levels of PAR may be a limiting factor for power line communication (PLC) where regulatory bodies have fixed the maximum amount of transmit power. Partial transmit sequence (PTS) is a well-known solution for PAR reduction, but its effectiveness depends on an accurate, and possibly error-free, exchange of side information (SI) betweendoi:10.1109/isplc.2007.371148 fatcat:w67xdmylq5hfjjtwwzvmgudvh4
