| description | A distortion cancellation device includes a first acquiring unit that acquires a plurality of transmission signals that are wirelessly transmitted at different frequencies; a second acquiring unit that acquires a reception signal to which an intermodulation signal generated due to the plurality of the transmission signals is added; and a processor that executes a process including acquiring a gain difference between the plurality of the transmission signals generated when the plurality of the transmission signals acquired by the first acquiring unit is sent to a generation source of the intermodulation signal, generating, by an arithmetic expression using both the acquired gain difference and the plurality of the transmission signals, a cancellation signal associated with the intermodulation signal, and combining the generated cancellation signal with the reception signal acquired by the second acquiring unit. |
