A radio communication apparatus 1 that can secure interference immunity, follow a transmission path variation, and prevent a decrease in transmission efficiency is obtained. The radio communication apparatus 1 that performs radio communication according to a multicarrier scheme includes: a transmitting unit 20 including a null inserting unit 203 that dispersedly arranges null symbols in a two-dimensional space of time and frequency in radio data, and a differential modulating unit 205 that performs differential modulation on a data symbol part other than the null symbols; and a receiving unit 30 including an interference measuring unit 305 that measures interference power for a data symbol that is a measurement target by using a null symbol adjacent to the data symbol in the two-dimensional space of time and frequency, and a delay detecting unit 306 that performs weighting on each data symbol according to the interference power measured for each data symbol and that performs delay detection between data symbols. |
