DISTORTION CANCEL DEVICE AND DISTORTION CANCEL METHOD

A distortion cancel device includes: a first acquiring unit that acquires a plurality of transmission signals including at least two transmission signals that are wirelessly transmitted at an identical frequency; a second acquiring unit that acquires a reception signal to which an intermodulation signal generated due to the transmission signals is attached; and a processor that executes a process including: determining a ratio of the transmission signals acquired by the first acquiring unit and wirelessly transmitted at the identical frequency; generating a ratio signal for each frequency from the transmission signals in accordance with the determined ratio; generating a cancel signal corresponding to the intermodulation signal by using an arithmetic expression that uses the generated ratio signal; and combining the generated cancel signal with the reception signal acquired by the second acquiring unit.
