1. A power-line communication apparatus, which belongs to a first communication system, for transmitting a multi-carrier signal including a plurality of sub-carriers through a power line, comprising:

  • a phase rotation section configured to rotate phase of at least one sub-carrier among the plurality of sub-carriers, by use of a first phase vector corresponding to the first communication system;

    a multi-carrier signal output section configured to output a first multi-carrier signal in which phase of at least one sub-carrier is rotated with the first phase vector within a first time slot corresponding to the first communication system;

    a band setting section configured to set up at least one of a time band and a frequency band on the basis of the first multi-carrier signal;

    a communication section configured to perform communication through the power line, by use of at least one of the time band and the frequency band, which are set up by the band setting section.
