A Fourier transform processor that is used in wireless communication includes: a Fourier transform mechanism including a butterfly unit and configured to perform a Fourier transform on data that is input to the Fourier transform processor; a first memory configured to store the data that is input to the Fourier transform mechanism; a first commutator configured to rearrange the data that is input to the first memory; and a second commutator configured to rearrange the data that is output from the first memory and that is input to the butterfly unit. This configuration allows the size and power consumption of the Fourier transform processor to be reduced. |
