Abstract
A modulator performs a predetermined operation for making an absolute value of an operation result of at least one element of an input signal greater than 0 on the individual elements of the input signal. The modulator generates post-operation data by associating individual elements of the input signal with individual elements of a data series which is a set of pieces of data which are equal in number to the elements of the input signal and whose absolute values are equal to one another, and multiplying the individual elements of the input signal which are subjected to the predetermined operation by the elements of the data series. An IFFT calculator performs inverse fast Fourier transformation on the post-operation data, and a synthesizer synthesizes operation results from the IFFT calculator to generate a baseband signal. A transmitter generates a transmission signal from the baseband signal and transmits the transmission signal.
