<p>A plurality of subcarriers (31) are assigned to a data channel (33). Subcarriers (32) the number of which is smaller than the number of the subcarriers (31) are assigned to a control channel (34). The control channel (34) is assigned to a center frequency (fc) of a frequency band used for transmitting the data channel (33). In this way, on the side of radio receiver apparatuses, the frequencies of local signals by which to multiply received signals can be made common, and the speed of switching between the control channel and the data channel can be raised.</p> |
