A transmitter in an OFDM system transmits signals to be received by each receiver individually, and signals to be received by a plurality of receivers commonly. A guard interval setting means sets a guard interval of the signals to be received by the plurality of receivers commonly to a length which is not shorter than the length of any guard interval of the signals to be received by each receiver. At the receiver, a guard interval control means sets a guard interval of the signals to be received by the plurality of receivers commonly to a length which is not shorter than the length of any guard interval of the signals to be received by each receiver, as a guard interval to be removed. |
