ABSTRACT:
A demodulation apparatus includes a first demodulator for receiving a first received subcarrier and demodulating it by a first demodulation mode, a second demodulator for receiving a second received subcarrier and demodulating it by a second demodulation mode, a third demodulator for demodulating composite subcarriers obtained by combining the first received subcarrier and the second received subcarrier by a third demodulation mode different from the first demodulation mode and the second demodulation mode, and a selector for selecting and outputting demodulation data of one of the first to third demodulators.
