A wireless communication apparatus includes a measuring unit, a matched filter, and a control unit. The measuring unit measures an electric power of a received signal. The matched filter is capable of operating as a first filter and a second filter for the received signal. The first and second filters detect a frame in a first and second communication channel, respectively. The second communication channel uses a frequency band including a frequency bands used in the first and third communication channel. The control unit determines whether or not the frame exists in the third communication channel according to a detection result of the measuring unit and the matched filter. The control unit operates the matched filter as the first filter when the frame exists in the third communication channel and operates the matched filter as the second filter when the frame does not exist in the third communication channel.
