It is provided a radio communication apparatus and radio communication method that, in the radio communication apparatus having a normal transmitting/receiving mode and a distortion correction mode, communicates successfully without influencing circuit characteristic in a normal transmitting/receiving mode, sends back a transmitting signal from the receiving system, extracts a distortion component due to narrowband characteristics or non-linear characteristics of a circuit, and corrects distortion in a distortion correction mode. In radio communication apparatus (100), distortion detecting section (111) extracts a distortion component using a transmitting baseband signal and a receiving baseband signal, coupling degree adjustment circuit (180) adjusts the degree of coupling between transmitting antenna (130) and receiving antenna (140), and coupling degree control section (170) switches the degree of coupling depending on a normal transmitting/receiving mode or a distortion correction mode.
