Abstract

A radio device includes: a processor that outputs a transmission signal containing a plurality of signals that are transmitted at different frequencies; an amplifier that amplifies the transmission signal output from the processor; and a transmitter/receiver that transmits by radio the transmission signal amplified by the amplifier and that receives by radio a signal having a frequency different from a frequency of the transmission signal. The processor generates a cancel signal based on the plurality of signals contained in the transmission signal, the cancel signal corresponding to an intermodulation distortion that occurs due to intermodulation among the plurality of signals, and the transmitter/receiver synthesizes the cancel signal generated by the processor with the transmission signal amplified by the amplifier.
