<P>PROBLEM TO BE SOLVED: To accurately correct the frequency error in reception signals, while suppressing the increase of a circuit scale and to prevent degradation in demodulation. <P>SOLUTION: A plurality of frequency offsets to be given to radio signals received in a radio receiving part 102 are determined in a frequency-offset determining unit 107; the determined frequency offsets are given to the radio signals in frequency-offset giving units 103-1 to 103-n; the radio signals, to which the frequency offsets are given are demodulated in demodulation units 104-1 to 104-n; an optional number of demodulation signals from the demodulated demodulation signals are combined, as the combined demodulation signals in demodulation signal combining units 105-1 to 105-(n-1); and one demodulation signal or combined demodulation signal is selected from among the demodulation signals and the combined demodulation signals in a demodulation signal selecting unit 106. <P>COPYRIGHT: (C)2009,JPO&INPIT |
