<p><P>PROBLEM TO BE SOLVED: To provide a mobile communication apparatus capable of reducing power consumption in a terminal, by enabling the work ratio of a subcarrier mapping portion to be controllable. <P>SOLUTION: From a scheduling section 20, a subcarrier mapping section 15 receives an instruction to which subcarrier a signal being output from a DFT section 14 is to be allocated, so as to perform IFFT in an IFFT section 16, and the signal is allocated to the instructed subcarrier position. At the time point when a "0" insertion position is decided by the instruction from the scheduling section 20, in an S/P conversion circuit, the subcarrier mapping section 15 fixedly outputs "0" instead of performing S/P conversion in regard to a "0" output portion. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
