Abstract
A modulator generates a modulation signal from an input signal, and a serial-parallel converter generates a subcarrier modulation signal from the modulation signal. An IFFT unit performs an inverse fast Fourier transformation on the subcarrier modulation signal, and a decomposer decomposes a calculation result into a real part data and an imaginary part data. A calculator applies a predetermined calculation with respect to each element the value of which is equal to or greater than a positive threshold value and each element the value of which is equal to or less than a negative threshold value among the real part data and the imaginary part data. A synthesizer synthesizes the real part data and the imaginary part data to generate a baseband signal, and a transmitter generates a transmission signal from the baseband signal, and transmits it to another apparatus via an antenna.
