To reduce the power consumption of a receiving apparatus. A first equalizer part (20) receives and equalizes a digital signal (202) and outputs a first equalizer part output signal (206). A first selector part (14) selects one of the digital signal (202) and first equalizer part output signal (206) to output it to a despread part (16) or a second equalizer part (22). The despread part (16) despreads its received signal, and a PSK demodulator part (18) PSK demodulates the despread signal. The second equalizer part (22) equalizes its received signal, and a CCK demodulator part (66) CCK demodulates its received signal. A second selector part (64) operates in accordance with the first selector part (14). A modulation scheme determination part (60) determines a modulation scheme by extracting, from the signal as demodulated by the PSK demodulator part (18), information related to the modulation scheme. A decision part (62) instructs, based on the determined modulation scheme, the signal selection by the first selector part (14) and second selector part (64). |
