1. A power-line communication apparatus for transmitting a multi-carrier signal including a plurality of sub-carriers to another communication apparatus 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 phase vector;

    a multi-carrier signal output section configured to output a multi-carrier signal in which phase of at least one sub-carrier is rotated with the phase vector;

    a band setting section configured to set up at least one of a time band and a frequency band, on the basis of the multi-carrier signal, which is outputted to a power line by the multi-carrier signal output section; and

    a communication section configured to perform communication with another communication apparatus through a 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.
