A communication device (transmitter (1)) communicates with a communication device (receiver (2)) constituting a multicarrier radio transmission system and having a function for measuring an interference noise power by using a null symbol inserted into reception data. The communication device includes a null signal insert unit (12) which places a predetermined number of null symbols in a data symbol storage region of a data frame to be transmitted to the receiver (2) so as to generate a data frame having the null symbols, thereby realizing a highly accurate interference power measurement in a data transmission section. |
