ABSTRACT:
A frequency correction circuit that gives plural frequency offsets to a received radio signal in order to correct a frequency error of the radio signal, demodulates the radio signal, combines an arbitrary number of demodulation signals as combined demodulation signals from among plural demodulation signals, and selects one demodulation signal or combined demodulation signal from among the demodulation signals and the combined demodulation signals.
