Signal generation device and signal generation method |
摘要 |
Disclosed is a signal generation device that employs a transmission method using inverse Fourier transform. The signal generation device includes: a modulation unit which modulates transmission data to obtain modulation data; a serial-parallel conversion unit which converts the modulation data input in series to parallel data of a predetermined size smaller than the size of inverse Fourier transform; a duplication unit which selects and duplicates all or a portion of the parallel data to obtain duplication data; a first time-axis shift unit which shifts the duplication data along the time axis to obtain time-axis shift data; and an inverse Fourier transform unit which carries out inverse Fourier transform on the parallel data obtained by the serial-parallel conversion unit and the time-axis shift data obtained by the first time-axis shift unit.
