Zusammenfassung:PROBLEM TO BE SOLVED: To provide a compact and inexpensive wireless communication device with the basic performance of the device enhanced, by eliminating or reducing an influence of intra-station transmission interference.SOLUTION: A wireless communication device includes: a first radio provided with functionality for transmitting and receiving a given high-frequency signal; a second radio provided with functionality for transmitting and receiving a given high-frequency signal; and a canceller section that includes: an amplitude-phase adjustment part for changing an amplitude or phase of an input high-frequency signal, or both thereof, by a given amount and outputting the result of changing; a first high-frequency direction adjuster, connected to the first radio and the amplitude-phase adjustment part, for outputting, to the amplitude-phase adjustment part, a high-frequency signal input from the first radio and outputting, to the first radio, the high-frequency signal input from the amplitude-phase adjustment part; and a second high-frequency direction adjuster, connected to the second radio and the amplitude-phase adjustment part, for outputting, to the amplitude-phase adjustment part, a high-frequency signal input from the second radio and outputting, to the second radio, the high-frequency signal input from the amplitude-phase adjustment part.
