ABSTRACT:
A receiving portion for receiving a wireless signal generated on the basis of a baseband signal having either a predetermined frequency band or a baseband signal having any of partial frequency bands; a signal processing portion for generating the baseband signal; a band shifter for shifting the frequency band of the baseband signal by such an amount of shift that the center frequency of at least a specific partial frequency band is in the vicinity of 0 Hz; a filter portion for outputting a partial signal, which is gained by sampling a signal component of the frequency band having a bandwidth of the specific partial frequency band with approximately 0 Hz as the center frequency, from the baseband signal; and a determining portion for determining the frequency band of the baseband signal on the basis of the partial signal.
