<p>Provided is a radio communication device capable of sufficiently removing a signal coming from the transmission side from a reception signal. The radio communication device includes: a cancel amplitude control unit (62) for selectively suppressing a cancel signal to a cancel signal synthesis unit (52); a reception signal end unit (50) for selectively terminating the reception signal input end (64i); a signal intensity detection unit (78) for detecting a signal intensity; a storage unit (82) for storing the signal intensity detected by the signal intensity detection unit (78); a signal intensity comparison unit (80) for comparing a plurality of types of signal intensity read from the storage unit (82); and a cancel signal control unit (72) for controlling the cancel signal amplitude and phase according to the comparison result obtained by the signal intensity comparison unit (80). Accordingly, it is possible to accurately detect the intensity of the reception signal by suppressing the cancel signal by the cancel amplitude control unit (62). On the other hand, by terminating the reception signal by the reception signal end unit (50), it is possible to accurately detect the intensity of the cancel signal.</p>
